Description

The RPWELL detector is a single-sided THGEM (copper clad on one side only) coupled to the readout electrode through a sheet of large bulk resistivity. In the last two years, laboratory and accelerator studies were performed in various single-element, RPWELL prototypes with a large variety of Ne- and Ar-based gas mixtures; these have demonstrated its large dynamic range (from single electrons to thousand-times MIPS), high gains (> 106), and high detection efficiency over a broad particle-flux range. The RPWELL operation under these conditions was stable, with MIP detection efficiency>98%, with no observable discharges. This makes it an attractive, industrially mass-produced detector for large-area applications in particle-, , astroparticle and nuclear physics, as well as in homeland security. We will further discuss the preliminary performance of RPWELL-based UV-photon detectors, with CsI-coated electrodes; among potential benefits for this application are the high sensitivity to single photoelectrons and large dynamic range (discharge-free operation under highly ionizing background).
