Abstract

The MPD Time-Projection Chamber (TPC) is the main tracking detector of the MPD experiment. Tracks coordinates are obtained by measurement of drift time of electrons from track position to readout chamber. The drift velocity of electrons can vary due to pressure, temperature, space charge effects, so it must be measured online. To solve this problem the laser calibration system is foreseen for this. The article presents an algorithm that provide drift velocity measurements and based on processing signal-in-time distributions.

执行 MPD TPC 电子漂移速度校准任务

摘要 MPD 时间投影室（TPC）是 MPD 实验的主要跟踪探测器。轨道坐标是通过测量电子从轨道位置到读出室的漂移时间获得的。电子的漂移速度会因压力、温度和空间电荷效应而变化，因此必须在线测量。为了解决这个问题，激光校准系统是可以预见的。文章介绍了一种基于时间信号分布处理的漂移速度测量算法。
