POLAR是一种紧凑的星载探测器，旨在对能量范围为50-500 keV的伽马射线暴等瞬态源的偏振进行可靠的测量。该仪器以康普顿散射原理为基础，沿着有多阳极光电倍增管，以塑料薄膜为主要探测材料。POLAR于2016年9月15日在中国空间实验室TG-2上成功发射。为了可靠地重建偏振信息，数据分析和蒙特卡罗研究都需要对仪器有非常详细的了解。为此，对在轨性能进行了全面研究，以获得仪器校准参数，如噪声、基座、电子设备的增益非线性、阈值、串扰和增益，以及温度对上述参数的影响。研究了多阳极光电倍增管的增益与高压的关系，给出了各种测量值的误差。最后用蒙特卡罗模拟方法估计了由于定标参数的测量误差而引起的伽玛暴偏振测量的典型系统误差。
POLAR is a compact space-borne detector designed to perform reliable measurements of the polarization for transient sources like Gamma-Ray Bursts in the energy range 50–500 keV. The instrument works based on the Compton Scattering principle with the plastic scintillators as the main detection material along with the multi-anode photomultiplier tube. POLAR has been launched successfully onboard the Chinese space laboratory TG-2 on 15th September, 2016. In order to reliably reconstruct the polarization information a highly detailed understanding of the instrument is required for both data analysis and Monte Carlo studies. For this purpose a full study of the in-orbit performance was performed in order to obtain the instrument calibration parameters such as noise, pedestal, gain nonlinearity of the electronics, threshold, crosstalk and gain, as well as the effect of temperature on the above parameters. Furthermore the relationship between gain and high voltage of the multi-anode photomultiplier tube has been studied and the errors on all measurement values are presented. Finally the typical systematic error on polarization measurements of Gamma-Ray Bursts due to the measurement error of the calibration parameters are estimated using Monte Carlo simulations.
