The DArk Matter Particle Explorer(DAMPE) is a satellite-borne detector for high-energy cosmic rays and y-rays. To fully understand the detector performance and obtain reliable physical results, extensive simulations of the detector are necessary. The simulations are particularly important for the data analysis of cosmic ray nuclei, which relies closely on the hadronic and nuclear interactions of particles in the detector material. Widely adopted simulation softwares include the GEANT4 and FLUKA,... 相似文献

在非相干多普勒测风激光雷达系统中,激光的线宽与频率的稳定性是影响测量结果准确性的两个重要因素。研制的激光雷达系统采用种子注入方法产生窄线宽脉冲激光,采用碘分子饱和吸收稳频的方法,利用VB语言基于PID算法编写仪器控制程序,将种子激光器的频率锁定在碘分子吸收线1 109线的高波数边缘上,长时间(4 h)锁频的精度0.5 MHz,频率的长期稳定度为3.5510-9。设计了连续光测速系统,得出多普勒频移测得的实验值与实际斩波盘的速度值曲线,速度误差小于0.4 m/s。由此也说明,所设计的连续光测速系统可以对整个锁频系统进行校准。该实验也为测风激光雷达的建设提供指导意义。 相似文献
