论文摘要
尖峰是高能X射线望远镜（HE）板上Insight-HXMT的原始光曲线上出现的明显急剧增加，这可能会对能量和功率谱等数据产品产生影响。它们被认为是由大信号产生的假触发器。在本文中，我们研究了尖峰的特征，并提出了两种从原始数据中删除尖峰的方法。根据对能量和功率谱的不同影响，选择并将其删除尖峰的最佳参数用于Insight-HXMT数据分析软件。还使用他在地面上检测到的备份来研究尖峰的发电机理，并且可以通过电子设计来降低尖峰。
Spikes are some obvious sharp increases that appear on the raw light curves of High Energy X-ray telescope(HE) onboard Insight-HXMT, which could have influences on the data products like energy and power spectra. They are considered to be fake triggers generated by large signals. In this paper, we study the characteristic of the spikes and propose two methods to remove spikes from the raw data. According to the different influences on energy and power spectra, the best parameters for removing the spikes is selected and used in the Insight-HXMT data analysis software. The generation mechanism of spikes is also studied using the backup HE detectors on ground and the spikes can be reduced by the electronic design.
