Title: Measurements of charge and light in pure high pressure Xe towards the study of Xe+TMA mixtures with dark matter directionality sensitivity and supra-intrinsic energy resolution for 0νββ decay searches

Abstract

Trimethylamine (TMA) may improve the energy resolution of gaseous xenon based detectors for 0νββ decay searches through the reduction of the Fano factor by the Penning effect. This molecule may also be the key for sensing directionality of nuclear recoils induced by Weakly Interacting Massive Particles (WIMPs) in monolithic massive (ton-scale) detectors, without the need of track imaging, by making use of columnar recombination. Nuclear recoil directionality may be the path for a definite discovery of the WIMP nature of Dark Matter. An ionization chamber has been constructed and operated to explore the properties of high pressure gaseous Xe + TMA mixtures for particle detection in rare-event experiments. The ionization, scintillation and electroluminescence (EL) signals are measured as function of pressure and electric field. We present results for pure xenon at pressures up to 8 bar. This work has been carried out within the context of the NEXT collaboration.
