It is with great joy that we can announce the outstanding achievement of our very own Matteo Ceschia, who has successfully defended his PhD thesis at University College London (UCL).

Meeting in Edinburgh

SuperNEMO collaborators gathered at the University of Edinburgh’s Pollock Halls this year for the summer collaboration meeting. Over three days, members presented their progress in areas like shielding, analysis, and software, and groups convened to discuss future SuperNEMO work. As a result of the communications discussion group, SuperNEMO now has a presence on Twitter @SuperNEMO_BB! Follow for exciting updates and photos of the collaboration.

January 2023 Meeting in Aussois

SuperNEMO members convened at the Fleurs et Neige Village in Aussois this January. In between great talks on a variety of experiment topics, collaborators took advantage of the lovely clear winter days to enjoy the ski slopes and mountain views. Such topics included updates on the demonstrator module and shielding plans, changes to the gas system, new ideas on Helium recirculation, and demonstrations of analysis techniques in flsimulate and with UDD format data.

Together again!

After more than two challenging years of the Covid-19 pandemic, collaborators reunited for an in-person collaboration meeting near SuperNEMO’s site in the French Alps.

Thank you, Rastislav

As the SuperNEMO Demonstrator commissioning continues, it’s vital to have a great team on site at LSM. With Covid restrictions disrupting international travel, this year has been challenging - so we were very lucky that researcher Dr Rastislav Hodák was able to spend six months working at LSM.

Our newest doctor - Veronika Palušová!

SuperNEMO is very proud of our latest PhD recipient - Dr Veronika Palušová! Veronika gained a joint doctorate from Comenius University in Bratislava and the University of Bordeaux when she defended her dissertation studying potential backgrounds to SuperNEMO’s double-beta-decay search.

Our first double-beta candidate!

Despite the huge challenges posed by the Covid-19 pandemic, SuperNEMO collaborators have been putting in huge efforts to get the SuperNEMO Demonstrator up and running at the LSM. It was a real joy to see a great result - our very first double-beta-decay candidate detected!

Congratulations Dr Ramón Salazar!

Hearty congratulations to the wonderful Dr Ramón Salazar, who has successfully defended his PhD thesis “Calibration and Monitoring Systems for Neutrinoless Double Beta Decay Searches in the SuperNEMO Experiment”.

SuperNEMO's Fedor Šimkovic wins Outstanding Scientist award

Miroslav's thesis scoops Dean's Award

On 14th of October 2019, the annual Dean’s award ceremony took place in the Faculty of Mathematics, Physics and Informatics, Comenius University in Bratislava, Slovakia.

NEMO by the sea

The SuperNEMO and NEMO-3 collaborations enjoyed their autumn collaboration meeting this October in a yet another gorgeous spot - the VVF holiday village in Lège-Cap Ferret, on the coast of the Arcachon Bay near Bordeaux in south-west France. The little cabins in the pine forest were a perfect setting for a productive meeting, and it was great to see some real progress on the detector, with commissioning continuing apace.

Congratulations, Dr Ashwin Chopra

Huge congratulations to Ashwin Chopra of University College London, who successfully defended his PhD thesis on May 1st. Ashwin studied the double-beta decay of molybdenum 100 in NEMO-3, looking for evidence of Lorentz violation. Deviations from the Lorentz invariance would break some of the most fundamental laws of physics, like Einstein’s theory of relativity, or the fixed speed of light in a vacuum. Thankfully, as far as we know, these theories still hold true!

Xin wins prize for SuperNEMO thesis

Xin Ran Liu has won the Astroparticle Physics group thesis prize at the Insititute of Physics Annual High-Energy Particle and Astroparticle physics conference in the UK. Xin did his PhD at UCL on low background techniques for SuperNEMO, and is now a postdoc at Edinburgh on LZ.

A sunny collaboration meeting in Annecy

For this spring’s SuperNEMO collaboration meeting, we were welcomed to LAPP, situated in beautiful Annecy, in the French Alps. There was lots to discuss, with a main highlight being the preliminary analysis our very first real live data, as we work on commissioning the SuperNEMO calorimeter walls.

NEMO-3 Quadruple Beta Decay paper selected by PRL editors

Our paper on the “Search for Neutrinoless Quadruple-$\beta$ Decay of $^{150}$Nd with the NEMO-3 Detector”, led by Dr Pawel Guzowski of the University of Manchester, has been chosen as an Editor’s Selection by Physical Review Letters. This is the first search for a decay mode predicted by some theories, which would violate lepton number conservation by four units. No evidence of the decay was seen, enabling us to set a limit on the half life for the process.

SuperNEMO collaboration meets in Prague

The SuperNEMO collaboration summer collaboration meeting took place this year from June 26-28 in Prague, Czech Republic. Physicists travelled across Europe and the world to discuss our progress at this exciting phase of the experiment, when we are installing and commissioning the detector, and preparing analysis software and simulation ready for first data in the coming months.

New SuperNEMO paper on the BiPo-3 detector

The SuperNEMO collaboration has published a paper containing measurements from the BiPo-3 detector. Located in the Canfranc Underground Laboratory in Spain, BiPo-3 is a low-radioactivity detector dedicated to measuring ultra low natural radionuclide contaminations of $^{208}$Tl ($^{232}$Th chain) and $^{214}$Bi ($^{238}$U chain) in thin materials. In particular, it has looked at the thin foils of selenium-82 that will be used as a double-beta decay source in the SuperNEMO experiment. It is vital that we study these decays from natural environmental sources, which can mimic our double-beta decay signal. BiPo-3’s results will be key to understanding these background processes so that we can achieve our goal of being an ultra-low-background experiment.

SuperNEMO and NEMO-3 detectors presented at TIPP

UCL researcher Dr Michele Cascella gave a presentation on the NEMO-3 and SuperNEMO experiments at the TIPP’17 conference. TIPP’17, the International Conference on Technology and Instrumentation in Particle Physics, took place in Beijing, China from May 22-26, 2017.

Congratulations, Dr Xin Ran Liu

Congratulations to Dr Xin Ran Liu, who defended his PhD thesis today, supervised by Professor Ruben Saakyan of University College London. Xin studied the effect of radon on SuperNEMO, studying the radiopure components that will lead to the ultra-low-background detector that we will need to make precision measurements of double beta decays.

Congratulations to Dr John Cesar

Congratulations are in order for Dr John Cesar, who defended his PhD dissertation today. John was supervised by Professor Karol Lang of the University of Texas at Austin.
