正在为 JET-EP2 增强功能开发用于伽马射线光谱诊断的本地控制和数据采集 (CDAQ) 子系统。硬件实现基于高级电信计算架构™ (ATCA™)，并且允许通过现场可编程门阵列 (FPGA) 上的数字脉冲处理 (DPP) 以非常高的计数率（高达几 MHz）进行采集，执行脉冲高度分析 (PHA)、脉冲形状鉴别 (PSD) 和堆积抑制 (PUR) 算法。本文介绍了 CDAQ 软件的实现，该软件基于 Euratom/IST 协会开发的 FireSignal 平台。 FireSignal 基于客户端/服务器模块化方法，其中服务器和硬件客户端均由通用 XML 描述定义。其事件驱动操作是动态的，从而允许连续控制和数据采集以及客户端/硬件的“即插即用”。 FireSignal 正在扩展，以将诊断子系统连接到 JET CODAS HTTP 数据/事件传输层，并集成诊断特定要求，包括硬件设备驱动程序、实时光谱处理和本地控制操作。
A local control and data acquisition (CDAQ) sub-system for gamma-ray spectroscopy diagnostics is being developed for the JET-EP2 enhancements. The Hardware implementation is based on the Advanced Telecommunications Computing Architecture™ (ATCA™) and will permit acquisition at a very high count rate (up to few MHz) with digital pulse processing (DPP) on a field programmable gate array (FPGA) performing pulse height analysis (PHA), pulse shape discrimination (PSD) and pile-up rejection (PUR) algorithms. This paper presents the CDAQ software implementation, which is based on the FireSignal platform developed by the Euratom/IST Association. The FireSignal is based on a client/server modular approach, where both the server and the hardware clients are defined by a generic XML description. Its event-driven operation is dynamic thereby permitting continuous control and data acquisition and ‘plug-and-play’ of clients/hardware. The FireSignal is being extended to interface the diagnostic sub-systems to the JET CODAS HTTP data/event transport layer and to integrate the diagnostics specific requirements including the hardware device drivers, real-time spectroscopy processing and local control operation.
