Abstract

The invention belongs to the technical field of photoelectron testing, and especially relates to a test platform for a silicon photomultiplier. The test platform comprises a light source system, a silicon photomultiplier system, a voltage control system and a collection and analysis control system. A circuit board of the silicon photomultiplier system is provided with a limiting frame corresponding to the silicon photomultiplier. The bottom of the limiting space of the limiting frame is provided with a contact point with a compression travel. In the testing process of the silicon photomultiplier, the silicon photomultiplier is disposed in the limiting frame, thereby achieving a purpose of putting the silicon photomultiplier at a determined position repeatedly, and facilitating the quick replacement of the silicon photomultiplier, the repeated measurement and the batch testing. The silicon photomultiplier is connected with the circuit board through the contact point with the compressiontravel, thereby achieving the flexible connection between the silicon photomultiplier and the circuit board, guaranteeing the reliability of the connection between the two sides, and preventing the silicon photomultiplier from being crushed or scratched in a process.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic testing, in particular to a silicon photomultiplier tube testing platform. Background technique [0002] The Positron Emission Tomography (PET) detector is the key device in the PET imaging equipment, and its main function is to obtain the position, time and energy information of the gamma photon deposition in the PET system. The performance of the PET detector directly determines the performance of the entire PET imaging system. In order to improve the imaging performance of the system, it is hoped that the positron emission tomography imaging detector used has high spatial resolution, good time resolution, and good energy resolution. Features such as high count rate. [0003] The function of the photoelectric converter in the PET detector is to convert the scintillation photons output by the front-end scintillation crystal into corresponding electrical pulses, and multiply and amplify th...
