Description
CYGNO is developing a high-precision gaseous Time Projection Chamber to be installed at the Gran Sasso National Laboratories (LNGS) for directional studies of rare low energy events, as dark matter. The detector consists in a TPC filled with He:CF4 gas mixture operating at atmospheric pressure with a triple GEM amplification stage. The gas scintillating properties allow the realization of an optical readout which comprises photomultipliers tubes and extremely low-noise granular sCMOS camera sensors. This technology provides a set of information on the recoil tracks, as released energy, 3D topology and position down to few keV of energy deposits, granting the advantages of a directional detector.
We will present the latest results on the underground operation at LNGS of a 50 l, 50 cm drift prototype focusing on the MonteCarlo-data comparison. In addition, we will show the design and features of the CYGNO demonstrator, a 0.4 m3 detector whose installation is foreseen for 2025 at LNGS.
