Abstract
Abstract
We are going to discuss the R&D and the prospects for the CYGNO project, towards the
development of an innovative, high precision 3D tracking Time Projection Chamber with optical
readout using He:CF4 gas at 1 bar. CYGNO uses a stack of triple thin GEMs for charge
multiplication, this induces scintillation in CF4 gas, which is readout by PMTs and sCMOS
cameras. High granularity and low readout noise of sCMOS along with high sampling of PMT allows
CYGNO to have 3D tracking with head tail capability and particle identification down to O(keV)
energy for directional Dark Matter searches and solar neutrino spectroscopy. We will present the
most recent R&D results from the CYGNO project, and in particular the overground commissioning of
the largest prototype developed so far, LIME with a 33×33 cm2 readout plane and 50 cm of
drift length, for a total of 50 litres active volume. We will illustrate the LIME response
characterisation between 3.7 keV and 44 keV by means of multiple X-ray sources, and the data
Monte-Carlo comparison of simulated sCMOS images in this energy range. Furthermore, we will
present current LIME installation, operation and data taking at underground Laboratori Nazionali
del Gran Sasso (LNGS), serving as demonstrator for the development of a 0.4 m3 CYGNO
detector. We will conclude by mentioning the technical choices and the prospects of the
0.4 m3 detector, as laid out in the Technical Design Report (TDR) recently produced by our
collaboration.
