KM3NeT collaboration: Off Sicily... ARCA
An operation to deploy 5 new ARCA (Astroparticle Research with Cosmics in the Abyss) detector lines has taken place in the infrastructure of the Italian KM3NeT site off Sicily.
This is a major step by the collaboration to build the telescope at the Italian site.
In total, six detection units are now in operation, representing the initial core of the KM3NeT/ARCA neutrino telescope. With the six ORCA detection units already taking data, the KM3NeT neutrino observatory has now comparable sensitivity to that of its predecessor, the ANTARES neutrino telescope.

A team of researchers, engineers, technicians and trainees from Subatech is directly involved in this operation through its participation in the commissioning of the telescope in its new form and in particular in the start-up and optimisation of all the acoustic elements that are indispensable for controlling its geometry and consequently its pointing accuracy.
A slightly more symbolic step was also accomplished for this optical module integration team. Indeed, one of the DOMs assembled in Nantes was sent urgently to Catania to replace a defective module on one of the lines prepared for this deployment. This is the first sensor assembled at Subatech to be in operation in the field, at a depth of 3500m.

News from POLLUSOLS program
With the creation of the OSUNA (Observatoire des Sciences de l'Univers de Nantes Atlantique) in 2008, the radiochemistry team of the Subatech laboratory positioned itself on environmental issues related to "nuclear" activities in the Loire catchment area (release of tritium from nuclear power plants, management of former uranium mines). The projects are now well structured at regional (POLLUSOLS programme), national (creation of the ZATU in 2015, collaboration with EDF, CEA-DAM....) and European (Radonorm) levels. At the regional level, the POLLUSOLS programme (2015-2021) funded by the Pays de la Loire region is coming to an end. It is in this context that several events are taking place:
- 16 april 2021
POLLUSOLS et la Région des Pays de la Loire organise a time of exchange on diffuse pollution
- 1st june 2021
Final conference POLLUSOLS
- 7 – 11 june 2021
Summer University POLLUSOLS 2021

IN2P3 collaboration with the Framatome Design School on advanced reactors
IN2P3 and Framatome have just signed a collaboration protocol involving three IN2P3 laboratories, the LPSC in Grenoble, the IJCLab in Orsay, Subatech in Nantes, and Framatome's Design School, a new entity created in early 2020 and integrated into Framatome's Advanced Reactor Competence Centre.
The Subatech researchers involved: Axel Laureau and Lydie Giot from the Nuclear Structure and Energy (SEN) team
