摘要：

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 x 10cm GEM and mu PIC. Using Ar+C2H6 (10%) gas, we achieved the gas gain of more than 10(5) 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 mu PIC readout systems.
