摘要:

正在开发一种用于植物成像应用的小型PET型检测器系统,其具有紧凑的硅光电倍增器(SiPM)阵列,以取代位置敏感光电倍增器(PSPMT)。除了紧凑性之外,SiPM的使用将允许涉及高强度MRI型磁场的成像设置。后者将允许在植物组织中的初始正电子湮灭的更好的位置分辨率。在目前的工作中,原型阵列进行测试,其响应的均匀性,因为它是已知的PSPMT需要显着的增益补偿上的各个通道,以实现改善的响应均匀性。初始测试表明,SiPM阵列可以在没有任何增益补偿的情况下使用的可能性很高。

英文摘要:

A mini-PET style detector system is being developed for a plant imaging application with a compact array of silicon photomultipliers (SiPM) replacing position sensitive photomultipliers (PSPMT). In addition to compactness, the use of SiPMs will allow imaging setups involving high strength MRI-type magnetic fields. The latter will allow for better position resolution of the initial positron annihilations in the plant tissue. In the present work, prototype arrays are tested for the uniformity of their response as it is known that PSPMTs require significant gain compensation on the individual channels to achieve an improved uniformity in response. The initial tests indicate a high likelihood that the SiPM arrays can be used without any gain compensation.
