为了评估用于正电子发射断层成像的液体氙气探测器的性能，我们在一台小型原型探测器上研究了511keV光子产生的闪烁光和电离电荷。用大面积雪崩光电二极管探测闪烁光，同时在漂移到3厘米后，电离电子被收集在用低噪声电子器件测量的阳极上。研究了电场对操作条件的影响。能源分辨率
In order to assess the performance of liquid xenon detectors for use in positron emission tomography we studied the scintillation light and ionization charge produced by 511 keV photons in a small prototype detector. Scintillation light was detected with large area avalanche photodiodes while ionization electrons were collected on an anode instrumented with low noise electronics after drifting up to 3 cm. Operational conditions were studied as a function of the electric field. Energy resolutions of
