作为星载探测器，POLAR 旨在对具有统计意义的事件样本进行伽马射线暴的硬 X 射线偏振测量，并且具有前所未有的精度。在其开发阶段，进行了许多测试、校准和验证测量，以验证仪器功能并优化操作参数。在本文中，我们介绍了增益优化的结果以及在广泛的实验室和环境测试过程中获得的验证数据。我们特别关注 137Cs 放射源的暴露以及旋光计所有 1600 个检测通道的增益对高电压的依赖性的确定。仪器的性能在动态范围、能量分辨率和温度依赖性方面进行了详细描述。还讨论了增益优化算法和响应不均匀性研究。下面给出的结果对于 POLAR 校准和操作数据库的开发非常重要。
As a space-borne detector POLAR is designed to conduct hard X-ray polarization measurements of gamma-ray bursts on a statistically significant sample of events and with an unprecedented accuracy. During its development phase a number of tests, calibrations and verification measurements were carried out in order to validate instrument functionality and optimize operational parameters. In this article we present results on gain optimization together with verification data obtained in the course of broad laboratory and environmental tests. In particular we focus on exposures to the137Cs radioactive source and determination of the gain dependence on the high voltage for all 1600 detection channels of the polarimeter. Performance of the instrument is described in detail with respect to the dynamic range, energy resolution and temperature dependence. Gain optimization algorithms and response non-uniformity studies are also discussed. Results presented below are important for the development of the POLAR calibration and operation database.
