CYGNO: an Optical TPC for the search of rare events

by Davide Pinci (ROMA1)

Monday 29 Mar 2021, 16:00 → 17:30 Europe/Rome

The search for a novel technology able to detect and reconstruct nuclear  and electron recoil events in the keV energy range has become more and  more important as long as vast regions of high mass WIMP-like Dark Matter  candidate have been excluded. Gaseous Time Projection Chambers (TPC) with  optical readout are very promising candidate combining the complete event information provided by TPC technique to the high sensitivity and  granularity of last generation scientific light sensors. CYGNO experiment  (a CYGNus module with Optical readout) is developing this approach  obtaining good energy and space resolution and a high sensitivity in the  keV energy range together with a very good particle identification useful  to distinguish nuclear recoils from electronic recoils. This experiment is  part the CYGNUS proto-collaboration which aims at constructing a network  of underground observatories for directional Dark Matter search. A 1 cubic  meter demonstrator is expected to be built in 2021/22 aiming to a larger  scale apparatus (30m$^3$-100 m$^3$), in a later stage.
