Description
We are going to present the CYGNO project for the development of an high precision optical readout gaseous TPC for directional Dark Matter search and solar neutrino spectroscopy, to be hosted at Laboratori Nazionali del Gran Sasso. CYGNO (a CYGNus TPC with Optical readout) fits into the wider context of the CYGNUS proto-collaboration, for the development of a Galactic Nuclear Recoil Observatory at the ton scale with directional sensitivity. CYGNO peculiar features are the use of sCMOS cameras and PMTs coupled to GEMs amplification of an Helium-based gas mixture at atmospheric pressure, in order to achieve 3D tracking with head tail capability and background rejection down to few keV energy and boost sensitivity to low WIMP masses. We will discuss the latest R&D results within the CYGNO project and the prospect for the upcoming underground installation of a 50 L prototype in Fall 2021, soon to be followed by a O(1) m$^3$ experiment in 2023-2024. We will illustrate the synergy with the ERC Consolidator Grant project INITIUM aimed at realising negative ion drift operation within the CYGNO 3D optical approach and how the reduced diffusion could boost the chosen approach towards large scale detectors.
