摘要:

POLAR是一种紧凑型偏振计,专门用于测量50-300 keV之间的伽玛暴的偏振。对200 × 6 × 6 mm ~ 3塑料棒的光收集进行了模拟和优化,以使单个塑料棒的不同点对X射线的响应均匀。蒙特卡罗结果表明,闪烁体表面的抛光程度和覆盖层对振幅均匀性的影响很大。一个非位置敏感的PMT和一个阵列的4X 4条构造的原型,实现了89%的均匀性。

英文摘要:

POLAR is a compact polarimeter dedicated to measure the polarization of GRBs between 50-300 keV. The light collection of 200*6*6mm3 plastic bars has been simulated and optimized in order to get uniform response to x-rays at different points of one single bar. According to the Monte Carlo results, the amplitude uniformity strongly depends on the polishing level of scintillator surface and the covering. A uniformity of 89% is achieved with a prototype constructed by a non position-sensitive PMT and an array of 4X4 bars.
