| 摘 要： | 由于EAST装置现有采集系统存在信号衰减,采样率较低等不足,利用同步采集卡PXI2022,结合Raid0磁盘存储技术,设计并实现了EAST装置软X射线采集系统。数据存储采用MDSplus,增强了通用性,便于国际交流。该系统已在2010年秋季EAST实验中得到成功运用。

| Abstract: | Aiming at the signal distortion and lower sampling rate in current EAST DAQ(Data Acquisition) System,This paper has designed and implemented soft X-ray data acquisition system of EAST based on PXI,by using the DAQ card PXI2022 and taking advantage of the RAID0 storage technique.In order to make international academic exchange,we stored the acquired data to the MDSplus database.This system was successfully applied in the EAST experiment in the autumn of 2010. |
