摘要:

低成本和高分辨率的多间隙电阻板室(MRPC)为基于飞行时间(TOF)的正电子发射断层成像(Positron Emission Tomography,正电子发射断层成像)系统的灵敏度在很大程度上取决于探测器的时间分辨率,为寻找有效的替代探测器开辟了新的可能性。在分层结构中,可以使用合适的转换器来增加光子检测效率。本文讨论了四间隙流注式酚醛树脂基MRPC和六间隙雪崩式玻璃基MRPC的宇宙线实验结果。

英文摘要:

The low cost and high resolution Multi-gap Resistive Plate Chamber (MRPC) opens up a new possibility to find an efficient alternative detector for the Time of Flight (TOF) based Positron Emission Tomography, where the sensitivity of the system depends largely on the time resolution of the detector. In a layered structure, suitable converters can be used to increase the photon detection efficiency. In this paper results of the cosmic ray test of a four-gap bakelite-based prototype MRPC operated in streamer mode and six-gap glass-based MRPC operated in avalanche mode are discussed.
