Abstract

A multiwire ionisation chamber filled with liquid xenon as a position sensitive detector for Positron Emission Tomography (PET) is studied. Both xenon scintillation, which provides a fast trigger, and ionisation charge for position and energy measurements are read. The detection efficiency of the detector is assessed by measuring separately the probability of detection of the scintillation light and the charge signals, due to 511 keV gamma-rays, being about 100% and 82% respectively
