Current newsletter: September 2019
(added on 23 September 2019)
Welcome back to the SuperNEMO Newsletter. We hope you all had a nice summer, and are ready to roll up your sleeves to get the detector running!
Recent Integration Progress
- OMs: All on-detector cabling has now been completed including X-Wall and Veto OMs.
- Light Injection System: has been installed and all optical fibres routed to optical modules (apart for the top Italian 5” row where blocs need to be drilled) . 4/8 reference OMs have been installed. Some work remains to install the reference radioactive sources, but the system is up and running has been used to help the calorimeter commissioning.
- Tracker cabling is complete, apart from the mountain-side external cables which are not yet installed in order to maintain easier access to the detector. Connections to the patchpanel have started.
- Gas-sealing has taken place, mainly on the French calorimeter main wall. Leak rates have been substantially reduced, but we still have some way to go before we have a sufficiently well-sealed gas-volume inside the tracker.
- Magnetic shields of the XV and VETO have been installed
- Calo FEB have been delivered and tested (including reflectometry + data readout checking). 7 caloFEB are at LAL for trigger testing.
- New scaffolding has been installed in front of the Italian MW (all the MW OM are accessible).
Recent Integration Challenges
- Week 40: final XV & VETO optical module testing.
- October: insertion of an endoscope through the calibration windows to visualise the inside of the detector after the sagging discovery.
- October/November: tracker HV installation & final cable plugging operations.
- October/November: tracker commissioning with HV.
- Final Gas leak checking: we still need a lot of help with this critical task. Please volunteer for this! Even with no prior experience, it will be extremely helpful to offer your time for this task.
Next weeks @ LSM (Need help !)

Shielding, coil, Anti-Rn tent
- Iron shielding: A quotation has been received from China. While less expensive than previous offers, half of the budget is missing. Several options are being investigated with Dubna and Prague to fix the issue with extra funding and/or machining outside China.
- Neutron shielding: 150 plates of pure polyethylene (validated with HPGe measurements performed this summer) have been produced in the Czech Republic and will be delivered to LSM in the next weeks.
- Coil has being pre-assembled at LAL last week (38) and will be installed at LSM starting week 47 (if green light from TB, i.e. if access to the detector is no longer required).
- Anti-Rn tent: HPGe measurements are in progress to validate the black PMMA plates.
Commissioning
- A lot of work has been done to characterize the OM (gain, baseline, timing…)
- A series of Co-60 source runs with the calorimeter ON have been performed this summer for commissioning and timing calibration studies.
- Data with the LI system have also been acquired.
Software & Analysis
- Regular analysis meetings are taking place: the last one was on 12th September 2019. Please plan on presenting an update on your analysis - contact Cheryl & Manu.
- A lot of work on the software infrastructure has taken place. The latest milestone is the release of Falaise 4.
- A dedicated effort is now needed on the calibration/reconstruction as well as on data quality and databases, getting ready for full data-taking.
- Need to implement new simulation features: bb source geometry, 7x6 calibration sources …
- An analysis workshop will be held before the Bordeaux collaboration meeting, on 15th October. Please plan on attending, where you can learn about and practice on the latest software developments for simulation and commissioning data analysis.
Management
- Yves is now based at LSM. This will greatly improve the smooth running of operations at LSM.
- For planning purposes, please remember to inform the DOG group (Alessandro & Yves) of your plans, 1 month in advance.
Congratulations
- To Ashwin Chopra (UCL) for successfully defending his thesis on 1st May 2019.
- To Xin Ran Liu (UCL) for winning an Institute of Physics prize for this thesis on 9th April 2019.
- To Yves and his family for the arrival of baby Augustin on 14th August 2019!
Save the date!
- The next collaboration meeting runs from 16-18th October near Bordeaux (with a pre-meeting analysis workshop on 15th October). Please [register ASAP] (https://indico.in2p3.fr/event/19118/)

Autumn 2018
(added on 23 November 2018)
Integration Milestones
A huge thanks to everyone involved in the following major milestones:
- The detector is closed! (see photograph to the left).
- Before closing, work was performed to repair tracker harnesses, optical modules and the replacement of the Nylon film in front of the calorimeter.
- A final check of the source deployment system confirmed that everything is still aligned following the attachment of the Italian tracker.
- All source foils were installed in September, and this week a 3D camera survey of the source foil has been performed: now there’s a big job for our software experts to describe the geometry in our simulation package!
- Almost half of the detector is now cabled (see photograph below).
Next weeks @ LSM
- Week 48: mainly tracker electronics work and further calorimeter work.
- Week 49: another busy week at LSM, with calorimeter electronics tests including initial data-taking with the French main wall, in parallel with preparations for gas leak-checking.
Next steps for the Experiment
- Gas-tightness: this is one of the biggest challenges we now face. We have started to discuss the strategy, but we will need help from many people.
- Cabling: a big task remains, especially the external cabling from the patch panels to the electronics racks for the tracker.
- Shielding: we need to finalise the design so that quotations can be obtained. A significant fraction of the funding is now secured, thanks to the help of our Dubna colleagues.
- Anti-radon tent: the design is complete, and the initial results on the materials look promising (Doc-DB 4771)
- Coil & magnetic field: plans for the coil installation need to be finalised. Magnetic shields need to be installed on X-Wall and Veto optical modules.
- Electronics, trigger & DAQ. Most of the hardware will soon be in place @ LSM, but a lot of work will be required to commission the full readout chain.
- Gas recirculation system. A useful meeting with ATEKO took place in Prague and we hope to see designs for this system soon.
Software and Analysis
- Manu (Cheryl) has now taken over as chair (deputy) of the Analysis Board. Many thanks to Yorck for his work leading this effort over the last 2 years.
- The last analysis meeting was held on 22nd November (minutes to be posted shortly).
- Ongoing studies : measuring backgrounds, shielding, gA, magnetic field, machine learning techniques, etc.
- Challenges for the near future will be to describe our real (not ideal!) detector including geometry from surveys, channel-by-channel efficiencies & resolutions, etc.
Management
- The Speakers Bureau and Publication Board membership has been renewed: Cheryl & Laurent will join the spokespersons, Ivan & Serge, with Karol in the chair. Many thanks to former members including Fabrice, Ruben & Jenny.
- LSM procedures are still developing under the new management of LPSC Grenoble. We will keep you informed of developments.
- For planning purposes, please remember to inform the DOG group (Alessandro & Yves) of your plans, 1 month in advance.
Congratulations!
- Jenny Thomas & Stefan Soldner-Rembold for winning prestigious UK Institute of Physics prizes (the Faraday and Chadwick prizes, respectively).
- Delphine Boursette and Guillaume Oliviero for passing their PhD vivas. Many thanks for all their contributions and we wish them all the best for the future!
Save the date !

June/July 2018
(added on 31 July 2018)
Integration @ LSM
- New plumb bobs and nests for the calibration deployment system have been installed and the first tests are successful.
- Tracker cabling : the first 16 tracker cable harnesses have been installed between the tracker feedthroughs and the patch panel.
- Gas sealing operations have been performed on the Italian calorimeter wall : nylon strips have been Stycast-ed on the back of the calorimeter bricks.
- Inspection of the nylon Italian film has demonstrated that it must be replaced. This operation will be done after the detector closure when the Italian calorimeter will be accessible again.
- Main French patch panels (both tunnel and mountain sides) and cable trunking has been installed.
- The Italian tracker and calorimeter frames have been moved back for the Bi calibration operations and the upcoming source foil installation.
Next operations @ LSM
- Final testing & verification of the calibration deployment system.
- Installation of the source foils (including removal of the tracker protection) weeks 37 and 38.
- Final testing of the calibration deployment system with the foils in place : week 38.
- Closure of the detector week 39 : sealing of the 2 tracker frames with the source frame.
Electronics, Trigger & DAQ
- Electronics commissioning at Manchester (week 26) from FEB to Trigger board has been successful.
- Ethernet routing has been designed (need further inputs from Tracker/LI/AD).
- Production of the calorimeter cables is in progress.
- Electronics rack equipment is being shipped to LSM.
- CMS commissioning started – VIRE-CMS communication checked.
Radon Tent/Gas-System
- Opaque materials are investigated (for mechanical and radiopurity concerns) to wrap (or build) the radon tent in order to be able to operate the detector in dark conditions for the period without shielding.
- A dedicated meeting on the gas recirculation system should be organised with ATEKO (Prague) during or just after the collaboration meeting.
Shielding
- A meeting with MRP-SYSTEM for the water tank option was held the 6th of July. Our mechanical constraints (particularly the 6 m height) are compatible with their system. Quotations for different thickness are under way.
- Results of simulations have confirmed that 160 cm of water are equivalent to 18 cm of iron for the gamma shielding and would be sufficient for both neutron and gamma backgrounds.
- Because of lack of space, this thickness of water cannot be installed all around the detector. Additional iron plates must be provided - suppliers are being investigated.
Calibration source characterisation
- The measurement of the 214-Bi sources with a high precision germanium detector has started in Bordeaux. Sources will be sent back to Modane week 35.
- New simulations with 7 sources per line for a total of 7x6 = 42 sources have been performed to evaluate the gain on the calibration accuracy and to determine the optimal positions. This proposal will be submitted to the collaboration after it has been exercised at Modane to evaluate the mechanical impact on the deployment system.
- Permanent installation (into the calibration lines) of the two available sources of 90-Sr (in place of two 214-Bi source) is also under consideration.
MC & Analysis
- Last analysis meeting held on 21 June 2018 (Minutes on DocDB 4679).
- Falaise 3.3.0 was released (with enhanced event generators) .
- Most of the MCC 2.0 samples were produced and are available at CCIN2P3 .
- Ongoing studies : shielding, gA, Magnetic field, Nd/Se, gamma tracking, energy corrections, calibrations…
Future Strategy Committee
- Last meeting held on 05 July (Minutes on DocDB 4678).
- First version of the FSC report has been reviewed.
- Short-term strategy will be completed particularly with the sensitivity on gA (ongoing study).

Software and computing
Working with the SuperNEMO software
All software is available under SuperNEMO-DBD
The main software package for offline work is Falaise. A guide to installing Falaise on Linux and macOS platforms is available through the dedicated Homebrew package manager and repo A starter guide to the core simulation, reconstruction and analysis tools available in Falaise can be found here.
Please note that the documentation is always under development, so feature requests
or contributions are welcome. For installation related issues when using brew,
use the SuperNEMO Brew Issue Tracker.
For all issues relating to using Falaise, or installing/developing it locally, raise an issue on the
Falaise tracker
Getting an account on the CCLyon computing cluster
The CCLyon computing cluster has a lot of simulation available from the MCC2 Monte Carlo challenge. To use it, you’ll first need to get an account.
If you already have one, make sure you can access it (and contact Yves if you can’t). If need an account follow this procedure:
- Visit this page and fill the form
- In Step 1 choose “Foreign collaborators” as Department and laboratory
- In Step 2 choose “nemo” as group and give a date 3 years from now for the Account’s expiration date (leave blank if you have a permanent position)
- In Step 3 download the form, sign in and send it to Yves
You should receive your account information in a few days.
Using CCLyon
Here are some instructions for logging onto CCLyon and getting started with the batch system that enables you to submit large jobs to the distributed computing cluster.
Website development
This site uses GitHub Pages to create a static website. It uses the following tools and techniques:
- Jekyll as the site generation engine
- GitHub Pages for hosting
- GFM and Kramdown for writing/parsing text
- MathJax for rendering math
Building locally
The website generated by Jekyll can be built and served locally to test changes without making commits upstream. Note that GitHub Pages has a soft limit of 10 rebuilds per hour. Provided you have an install of Ruby 2 or better, including the development headers and library, the workflow is:
$ git clone https://github.com/supernemo-dbd/supernemo-dbd.github.io
$ cd supernemo-dbd.github.io
$ ./snjekyll serve
The last command will download and setup the local Jekyll instance, and start a local isolated webserver at http://127.0.0.1:4000. Simply point your favoured browser to this address to view the generated site.
The server runs in the foreground and watches the site sources for changes (for example, index.md). When a file changes, the server will rebuild the site automatically, so simply refresh your browser to see the resultant regenerated site. For example, try making some changes to index.md. The server may be shutdown at any point using Ctrl-C.
Further information on tasks available from snjekyll can be seen by running
$ ./snjekyll help
Alternately, if you already have a custom Ruby install, e.g. with Home/Linuxbrew you can do
$ git clone https://github.com/SuperNEMO-DBD/SuperNEMO-DBD.github.io
$ cd SuperNEMO-DBD.github.io
$ gem install bundler
$ bundle install
$ bundle exec jekyll serve
In both workflows, the xz package installed by Home/Linuxbrew is not compatible with the nokogiri gem required by Jekyll, and will cause compiliation of the gem to fail. snjekyll will issue a warning about this, but will not take further action. To work around this issue, either do brew unlink xz or remove Home/Linuxbrew settings from your environment. The latter may not be possible if you have Homebrew installed in /usr/local
Can we use MathJax and \(\LaTeX\)?
MathJax can support inline math, e.g. \(1/x^2\), and block equations:
\[e^{i\pi} + 1 = 0\]like the above. Numbered equations, using the AMS math environment:
\[\begin{equation} E = mc^2 \label{einstein} \end{equation}\]This should allow a reference (see Equation \(\eqref{einstein}\)) to be inserted.
Can we use code blocks?
Here’s C++:
#include <iostream>
int main() {
std::cout << "Hello World\n";
}
and some Python:
import os
print('Hello World')

Operations
Working at LSM
As we enter the final stages of construction and commissioning, everyone is welcome and needed at LSM. Here are some hints to ensure your trip is drama-free. If you have questions about the integration and running management, contact Yves and Alessandro.
Register on the calendar
There will always be something for you to do! Let us know when you are available to travel to LSM by registering on the calendar. Yves can get you an account. Instructions for the calendar are on docDB 4555. Make sure Yves, Alessandro and Andrea know which days you will be able to go underground at least 1 week in advance, so that they can add you to the LSM calendar and arrange for a driver. If you would like to eat lunch underground, let them know - but it can’t be guaranteed, as it depends on driver schedules.
Going underground
The cars going to the underground lab leave at 8:30am each day, so be sure to arrive at the surface lab on time. If you plan to stay all day, bring your own lunch - there’s a fridge, microwave, kettle and espresso machine underground, as well as clean drinking water (in bottles).
If you are not eating lunch underground, you will leave for lunch on the surface by 11:30am. If returning to the tunnel for the afternoon, departure will be 1:30pm from the surface lab.
If you’re staying late, you’ll need to get permission from the lab management - your driver should be able to help you. The LSM drivers normally leave the underground lab for the evening at around 4:30 or 5pm, but if you have a SuperNEMO driver, you might be able to stay later.
Training
Before you go underground for the first time, you will need to do some basic safety training, in case there is an emergency in the tunnel. Jean-Lou of LSM leads this training, and you will be able to do it very quickly in the morning before you go underground. You will also need to receive some security paperwork. To get all of this set up, let Valerie Favre know that you will be going underground for the first time.
Staying in Modane
You have a few options for accommodation in Modane. The cheapest option is to stay in the LSM dorms. There are 4 rooms in the basement of the surface lab. Each one has its own shower and toilet, and there is a shared kitchen which is stocked with basic cooking equipment. The dorm rooms cost EUR19 per night. To find out about availability and book a room, contact Valerie Favre at LSM. Alternatively, people choose to stay in Modane itself (walking distance to the lab) or in the nearby ski resort of Aussois, a 10-15 minute drive from the lab. Some hotels we have tried:
- Hotel Le Commerce in Modane
- Les Voyageurs in Modane
- Les Mottets in Aussois
- Hotel du Soleil in Aussois
Modane and Aussois both have restaurants, although some of them will be closed in the non-tourist season. Modane’s gastronomic district (such as it is) is the street by the railway station. A few we like:
- Il Peppuccio Pizzeria in Modane. No trip to LSM is complete without a Peppuccio pizza. Veggie options available. Gluten-free possible but limited.
- L’Echappee A little more expensive, with French food including Alpine specialities. Go there when you want to celebrate.
- Pulcinella A pizzeria that is not Peppuccio. Sometimes open when Peppuccio is closed.
- Le Perce Neige Traditional food of the Savoie region. Lots of cheese. Feels like somebody’s living room.
- L’international Turkish food. Exotic by Modane standards!
- Hotel de la Gare Sells crepes and galettes, among other things.
Getting to Modane
The easiest way to get to Modane is probably to fly to either Geneva or Lyon St-Exupery, and rent a car. It’s around a 2.5-hour drive to the lab from either of these, mostly on motorways, although the travel time can vary significantly with traffic. There is parking at the lab and street parking near the hotels, though finding spaces in downtown Modane can be annoying.
The TGV from Paris Gare-de-Lyon to Turin stops in Modane, but the trains are not frequent. It’s about a 4-hour ride from Paris. For more flexibility in timing, you can consider changing at Chambery and using a local train for the Alpine part of the trip. There is also a TGV from the Lyon airport - again, infrequent - if you don’t want to drive. Getting to and from Geneva or Turin airports by public transport is harder, but possible.
Things to consider
It is warm in the tunnel! Choose comfortable and cool clothing to wear under your cleanroom suit. Be sure to stay hydrated. (There is drinking water available underground.) If you will be coming frequently, consider investing in your own pair of steel-toed cleanroom shoes. I use Honeywell brand. Otherwise, you can borrow someone’s shoes, but you might not find a pair in your size. The other items of clothing (cleanroom suit, plus disposable hair net, mask, and gloves) are already at the LSM, with a selection of suit and glove sizes available.
When you are underground but not in the cleanroom, you must wear closed-toed shoes. No sandals!
There is no wi-fi underground, but you can connect to the internet using an ethernet cable (in the break room). You should turn off your phone or put it in airplane mode when you are underground, to protect other experiments in the lab.
