DAMPE硅跟踪仪星载数据压缩算法
DAMPE silicon tracker on-board data compression algorithm
摘要：
暗物质粒子探测器（DAMPE）是一颗即将发射的科学卫星，用于探测高能伽马射线、电子和宇宙射线。硅跟踪器（STK）是DAMPE有效载荷的子探测器，具有出色的位置分辨率（读出间距为242 μ m），可测量粒子的入射方向以及电荷。STK由12层硅微带探测器（SMD）组成，相当于6.5 m $^2$的总硅面积。STK的总读出通道数为73728，这导致了大量的原始数据需要处理。在本文中，我们专注于星上的数据压缩算法和程序的STK，这是初步验证宇宙线测量。
英文摘要：
The Dark Matter Particle Explorer (DAMPE) is an upcoming scientific satellite mission for high energy gamma-ray, electron and cosmic rays detection. The silicon tracker (STK) is a sub detector of the DAMPE payload with an excellent position resolution (readout pitch of 242um), which measures the incident direction of particles, as well as charge. The STK consists 12 layers of Silicon Micro-strip Detector (SMD), equivalent to a total silicon area of 6.5m$^2$. The total readout channels of the STK are 73728, which leads to a huge amount of raw data to be dealt. In this paper, we focus on the on-board data compression algorithm and procedure in the STK, which was initially verified by cosmic-ray measurements.
