摘要

为联合欧洲环面(JET)开发了一种新的伽马射线诊断数据采集(DAQ)子系统。该系统基于ATCA平台，能够以14位分辨率采样多达400 MSPS。该DAQ用于伽马射线诊断，专门用于研究聚变托卡马克等离子体实验中的快离子。本工作描述了用于从DAQ自由运行的ADC数据流中提取脉冲参数的脉冲处理算法的发展。这些算法分为三个主要功能模块，即高级触发和分割，分割验证，最后是峰高分析(PHA)和堆积拒绝(PUR)。

Pulse analysis for gamma-ray diagnostics ATCA sub-systems of JET tokamak

A new Data Acquisition (DAQ) sub-system for gamma-ray diagnostics was developed for Joint European Torus (JET). The system is based on the ATCA platform and is able to sample up to 400 MSPS with 14-bit resolution. This DAQ is used for gamma-ray diagnostics dedicated to the study of fast ions in fusion tokamak plasma experiments. The present work describes the development of pulse processing algorithms used to extract the pulse parameters from the DAQ free running ADC data streams. These algorithms are divided in three main functional blocks, namely, advanced triggering and segmentation, segmentation validation and finally, peak height analysis (PHA) and pile-up rejection (PUR).
