摘要：
Some results of a study of the properties of a low pressure multistep avalanche chamber with BaF2 scintillators and with TMAE as the photosensitive gas for a 3D PET scanner are presented. Absolute gas amplification was carefully measured by two independent methods, giving rise to a maximum attainable total gain of the order of 10(7). A typical electron transmission efficiency of 20-30% was obtained. The time resolution of the detector can be optimized to be approximately 6 ns FWHM.
