Abstract

A new type high spatial resolution radiation detector based on a UV scintillatora UV imaging gas photomultiplier is presented. The prototype UV detector consists of a 10 cm×10 cm μPIC, 2 GEMs and a semitransparent CsI photocathode deposited on a MgF₂ window. The effective photo-sensitive area is φ34 mm and the readouts are 400 μm pitch strips. A newly developed 20 mm size LaF₃(Nd) crystal which emits 172 nm photons is coupled to the detector for the first step. The detector was tested in pulse mode operation with 5.5 MeV α particles from ²⁴¹Am. The single photoelectrons were successfully detected and the images of the crystal shape were clearly obtained.
