Abstract
Abstract
The first operation of a cryogenic Resistive Plate WELL
(RPWELL) detector in the saturated vapor of liquid argon is
reported. The RPWELL detector was composed of a Thick Gas Electron
Multiplier (THGEM) electrode coupled to a metallic anode via
Fe2O3/YSZ ceramics (Fe2O3 in weight equal to 75%),
with tunable bulk resistivity in the range
109–1012 Ω·cm. The detector was operated at
liquid argon temperature in saturated argon vapor (90 K, 1.2 bar)
and characterized in terms of its effective charge gain and
stability against discharges. Maximum stable gain of G≈17
was obtained, without discharges. In addition, preliminary results
from novel 3D-printed thermoplastic plates doped with carbon
nanotubes are presented.
