Mrs Rita J C Roque (LIBPhys, Deparment of Physics, University of Coimbra, 3004-516 Coimbra, Portugal), Mr R Daniel P Mano (LIBPhys, Department of Physics, University of Coimbra, 3004-516 Coimbra, Portugal)

20/12/2021, 16:20

Following the former studies on He-CF4 (60/40) mixtures with the addition of isobutane percentages from 1- 5%, on the search for the gas mixture that at best enhances the electroluminescence (EL) gain while minimizing the detector operation instabilities owing to the addition of isobutane, we varied the ratio of CF4-to-He for two different isobutane contents, namely 2% and 5% and studied the...

10. Molecular sieve-based gas recycling system with radon reduction for rare-event gaseous detectors

21/12/2021, 14:20

A new molecular sieve-based gas recycling system is presented that provides for simultaneous removal of both radon and common impurities from SF$_6$:CF$_4$:He gases in TPCs, hence minimising the total amount of gas required. Removal of internally-produced radon and associated progeny is important for background suppression whilst removal of outgassing and leaked-in contaminants such as water,...

1. Direct detection for CYGNO

Giovanni Grilli di Cortona (INFN - LNF)

21/12/2021, 14:40

I will review the concepts of direct detection of dark matter, for both spin independent and spin dependent interactions, relevant for the CYGNO experiment. In particular, I will discuss the possibility to improve the sensitivity exploiting the Migdal effect.
