Abstract
A multiwire ionisation chamber filled with liquid xenon as a position sensi tive detector for Positron Emission Tomography is studied. Both xenon scint illation, which provides a fast trigger, and ionisation charge for position and energy measurements are read. The detection efficiency of the detector is assessed in separate measurements of the probability of detection of th e scintillation light and the charge signals due to 511 keV gamma-rays. The se were measured to be about 1 and 0.82, respectively.
