Abstract

We are developing a new type of photon detector for an experiment searching for muon decays to positron and gamma with the sensitivity of 10-14 branching ratio by using the world most intensive continuous muon beam provided at PSI. In this experiment the photon detector utilizes liquid xenon as scintillation material because of its fast response, large light output yield, and high density. Scintillation light emitted in liquid Xe is directly observed by photomultipliers (PMTs) located in liquid without any transmission window in order not to lose light yield. To study the detector response to gamma rays we constructed a prototype with an active volume of 2300 cm3 surrounded by 32 PMTs. The PMT was newly developed so as to be operated even in liquid Xe at 165K. Energy, position, and timing resolutions have been evaluated with gamma-ray sources from 320keV to 1835keV. Performance of the prototype is presented in this article.
