POLAR是一种多通道位置灵敏探测器,用于探测伽玛射线暴(GRB)光子的偏振特性。我们已经设计了一个原型的POLAR前端电子(PFEE)的专用集成电路(ASIC)的基础上,具有大动态范围和低功耗。使用脉冲发生器和α射线源测量PFEE的性能。PFEE原型的实测平均等效噪声电荷(ENC)和输入信号动态范围分别为6.7fC(rms)和9pC。实验结果表明,PFEE的主要功能已经实现,使该原型可以在未来的实验。
POLAR is a multi-channel position-sensitive detector used for polarization property detection of gamma-ray burst (GRB) photons. We have designed a prototype of POLAR front-end electronics (PFEE) based on Application Specific Integrated Circuits (ASICs) with large dynamic range and low power consumption. The performances of PFEE are measured using a pulse generator and an alpha-ray source. The measured average Equivalent Noise Charge (ENC) and input signal dynamic range of the PFEE prototype are 6.7fC (rms) and 9pC, respectively. The results that are obtained show that the main functions of the PFEE have been achieved, making this prototype usable in future experiments.
