The JOINBON Silicon Photomultiplier is a novel commercial silicon sensor for weak photon flux. In this paper we report a characterization of the sensor for the readout of LySO crystals with potential application to Positron Emission Tomography. We measured a energy resolution of approximately (13.50±0.03)% (FWHM) and a coincidence time resolution ranging between (215±3) ps for a 5 mm long crystal up to (290±2) ps for a 20 mm long crystal. Finally we tested the feasibility of the JOINBON SiPM to a Multi Voltage Threshold readout and we obtained a energy resolution compatible with the intrinsic system performance.

用于读出LySO晶体的JOINBON SiPM：多电压阈值方法

JOINBON硅光电倍增器是一种用于弱光子通量的新型商用硅传感器。在本文中，我们报告了用于读出LySO晶体的传感器的特性，并有望应用于正电子发射断层扫描。我们测得的能量分辨率约为（13.50±0.03）％（FWHM），同时时间分辨率介于5mm长的晶体的（215±3）ps和20mm长的晶体的（290±2）ps之间。最后，我们测试了JOINBON SiPM到多电压阈值读数的可行性，并获得了与固有系统性能兼容的能量分辨率。
