Abstract The JET control and data acquisition system (CODAS) is an integrated system that provides all the pulse based and continuous data acquisition, real time and slow control and control room interfaces for JET. It has a long history, dating back to the beginning of JET in 1980. It utilises both commercially available hardware along with many in-house modules. The software has grown up and evolved largely independently of other developments in big science. Similarly, the data acquisition system on MAST has a long history of evolution from previous facilities at Culham (COMPASS). It utilises commercially available and in-house hardware (some shared with JET CODAS) and software that has developed largely independently of JET and other external developments. More recently, we have begun to adopt some ITER CODAC relevant technologies on both JET and MAST, in part, to also introduce some standardisation between the two facilities. This started with a pilot project to create a cubicle and environment monitoring system using commercial hardware and EPICS monitoring and HMI. We have since gone on to implement several camera and spectrometer filter controllers, several types of turbomolecular pump controller, and various radiation protection monitors in EPICS on JET. We are also implementing a central information display system for MAST that links the OPC interface on the machine control through to several display screens showing the machine state using EPICS. We have several MARTe based real time applications on JET and are now developing an application to provide real time processing of high-resolution Thomson scattering data using MARTe V2 (an ITER/F4E initiative to improve the robustness of this real-time framework). We are also considering upgrading the existing MARTe applications to this version. On JET we have also started to use another ITER CODAC technology – SDN to supplement the ATM based real time control network on JET. Initially, as a proof of principle, a real time plasma profile display was implemented. This system is now being extended to include several real time data sources which will feed their data back into the ATM network and on to the real time controllers. Looking forward, we anticipate extending the JET real time network with a purely ITER CODAC/SDN connected real time control system and provide a richer ITER CODAC interface to the JET CODAS to accommodate the possibility of ITER diagnostics testing and provide a real stress test for ITER archiving technologies.

JET和MAST上ITER CODAC相关技术介绍

摘要 JET控制和数据采集系统（CODAS）是一个集成系统，为JET提供所有基于脉冲的连续数据采集、实时和慢速控制和控制室接口。它有着悠久的历史，可以追溯到 1980 年 JET 的诞生之初。它利用了商用硬件和许多内部模块。该软件的成长和发展在很大程度上独立于大科学的其他发展。同样，MAST 上的数据采集系统从 Culham (COMPASS) 以前的设施发展而来也有很长的历史。它利用商用和内部硬件（一些与 JET CODAS 共享）和在很大程度上独立于 JET 和其他外部开发而开发的软件。最近，我们已经开始在 JET 和 MAST 上采用一些 ITER CODAC 相关技术，部分是为了在两个设施之间引入一些标准化。首先是一个试点项目，该项目使用商业硬件和 EPICS 监控和 HMI 创建隔间和环境监控系统。从那以后，我们继续在 JET 上的 EPICS 中实现了几个相机和光谱仪过滤器控制器、几种类型的涡轮分子泵控制器和各种辐射防护监视器。我们还为 MAST 实施了一个中央信息显示系统，该系统将机器控制上的 OPC 接口连接到使用 EPICS 显示机器状态的多个显示屏。我们在 JET 上有几个基于 MARTe 的实时应用程序，现在正在开发一个应用程序，以使用 MARTe V2（ITER/F4E 计划，以提高该实时框架的稳健性）提供高分辨率汤姆森散射数据的实时处理。我们也在考虑将现有的 MARTe 应用程序升级到这个版本。在 JET 上，我们也开始使用另一种 ITER CODAC 技术——SDN 来补充 JET 上基于 ATM 的实时控制网络。最初，作为原理证明，实施了实时等离子体轮廓显示。该系统现在正在扩展以包括几个实时数据源，这些数据源将它们的数据反馈到 ATM 网络和实时控制器。期待，
