ITER软X射线相机冷却实验监控系统

Monitor and Control System of Cooling Experimental for ITER Radial X-Ray Camera

作为ITER重要的物理诊断之一,软X射线相机在装置烘烤时将面临高达250℃的环境温度。因此,冷却上限温度仅为75℃的相机探测器至关重要。为了验证冷却效果,所进行的冷却实验采用基于EPICS的监控系统管理实验过程及结果,实现了数据采集、存储、检索以及设备控制等功能,本设计创新之处在于高效的将所有采集控制算法通过EPICS集中实现。本文对监控系统的功能需求、监控参数、硬件及软件设计和测试结果进行了详细描述。结果表明,监控系统运行稳定,不仅为软X射线相机冷却实验提供可靠支撑,也为EPICS在监控系统中的推广提供借鉴。

As one of the most important physical diagnosis of ITER, Radial X - Ray Camera （RXC） will face a 250℃ high temperature when ITER is baking. Therefore, it is very important for the cooling of the detectors in Radial X - Ray Camera as whose ceiling temperature is 750℃. In order to verify the effect of cooling, an EPICS based monitor and control system is developed for the management of cooling experiment process and results. The functions for data acquisition, storage, retrieval and device control are realized with the help of monitor and control system. The most creative work is that all the acquisition and control algorithms are achieved through EPICS. In this paper, the functional requirements, monitoring parameters, hardware and software design and test results of the monitor and control system are described in detail. Test results show that the monitor and con- trol system is stable. It not only provides reliable support for the cooling experiment of BXC, but also gives ref- erences for the popularization of EPICS in monitoring system.
