论文摘要
由1/2英寸CE制成的紧凑型X射线探测器：已为Riken-ral的Famuexperiment开发了带有SIPM阵列读数的LABR3立方体形状的晶体，以使其进入困难的仪器区域。由于CE的高光子产率：LABR3，因此可以基于CAEN V1730数字化器使用简单的读数方案，而无需专门的扩增阶段。通过使用CAEN A7885D调节的电源芯片和温度反馈来纠正SIPM增益温度的漂移。在137cs峰值下3：5％的能源分辨率（FWHM）获得了57CO峰值的9％。
Compact X-rays detectors made of 1/2 inch Ce:LaBr3 crystals of cubic shape with SiPM array readout have been developed for the FAMUexperiment at RIKEN-RAL, to instrument regions of difficult access. Due to the high photon yield of Ce:LaBr3 it was possible to use a simple readout scheme based on CAEN V1730 digitizers, without a dedicated amplification stage. The drift with temperature of SiPM gain was corrected by using CAEN A7885D regulated power supply chips with temperature feedback. Energy resolutions (FWHM) around 3:5% at the 137Cs peak and around 9% at the 57Co peak were obtained.
