Abstract

A new large area UV photon detector with micro pattern gaseous detectors is developed and evaluated. A semitransparent CsI photocathode deposited on a MgF₂ window was combined with 10cm × 10cm GEM and μPIC. Using Ar+C₂H₆ (10%) gas, we achieved the gas gain of more than 10⁵ which is enough to detect single photoelectron. We, then, irradiated vacuum UV photons (VUV, around 172nm) from the newly developed LaF₃(Nd) scintillator to the detector and the single photoelectrons were successfully detected. We also demonstrated the imaging capability of the detector with μPIC readout systems.
