Skipper CCD technology has recently unlocked unprecedented sensitivity to ionization signals as faint as a single electron, enabling new frontiers in direct dark matter searches. As a result, the DAMIC-M experiment at the Modane Underground Laboratory, based on Skipper CCDs, has delivered the most stringent constraints to date on sub-MeV dark matter interacting with electrons, probing both freeze-out and freeze-in scenarios in the dark sector for the first time. While Skipper CCDs represent a technological breakthrough by overcoming the readout noise floor of conventional CCDs, they do so at the cost of readout time. New recent improvements, including MAS-CCD, SiSeRO, and CMOS Skipper architectures, combine faster readout with Skipper-level performance. I will detail those and focus on the possibility of designing a future low-noise imager using Skipper CMOS technology.

Retour à l'agendaA first look at neutrino oscillations with JUNO
Speakers: João Pedro Athayde Marcondes de André (IPHC), Loic Labit (LP2IB-CNRS) The Jiangmen Underground Neutrino Observatory (JUNO) is a multipurpose observatory located in China that came online in the middle of 2025. The JUNO detector consists of a 20kton liquid scintillator target monitored by about 18k 20 inch PMT and about 26k 3 inch PMT. This detector is strategically located 53 km from the Taishan and Yangjiang Nuclear Power Plants in order to precisely measure reactor anti-neutrino oscillations. The first results from JUNO, using 2 months of data, significantly improve the precision of two of these parameters. This seminar will cover the performance and first results from JUNO. https://indico.in2p3.fr/event/39039/
