Plasma diagnostics systems are becoming progressively more advanced. Contemporarily, researchers strive to achieve longer plasma pulses, and therefore, appropriate hardware is required. Analogue-to-Digital Converters are applied for data acquisition in many plasma diagnostic systems. Some diagnostic systems need data acquisition with gigahertz sampling frequency. However, gigasample digitizers working in continuous mode generate an enormous stream of data that requires suitable, high-performance processing systems. This becomes even more complicated and expensive for complex multi-channel systems. Nonetheless, numerous plasma diagnostic systems operate in a pulse mode. Thomson scattering (TS) diagnostics is a good example of a multi-channel system that does not require continuous data acquisition. Taking this into consideration, the authors decided to evaluate the CAEN DT5742 gigasample digitizer as a more cost-effective solution that would utilize the pulsed nature of the TS diagnostic system. The paper presents a complete data acquisition and processing system dedicated for plasma diagnostics based on the ITER real-time framework (RTF). Integration of RTF with real hardware is discussed. The authors of the paper have developed software including RTF function block for the CAEN DT5742 digitizer, example data processing algorithms, data archiving and publishing for plasma control system.

评估用于脉冲千兆样本数字化仪数据采集和处理的 ITER 实时框架

等离子体诊断系统正变得越来越先进。同时，研究人员努力实现更长的等离子体脉冲，因此需要适当的硬件。模数转换器应用于许多等离子体诊断系统中的数据采集。一些诊断系统需要以千兆赫采样频率采集数据。然而，在连续模式下工作的千兆样本数字化仪会生成大量数据流，需要合适的高性能处理系统。对于复杂的多通道系统，这变得更加复杂和昂贵。尽管如此，许多等离子体诊断系统仍以脉冲模式运行。汤姆森散射 (TS) 诊断是不需要连续数据采集的多通道系统的一个很好的例子。考虑到这一点，作者决定将 CAEN DT5742 千兆样本数字化仪评估为一种更具成本效益的解决方案，它将利用 TS 诊断系统的脉冲特性。本文提出了一个完整的数据采集和处理系统，专用于基于 ITER 实时框架 (RTF) 的等离子体诊断。讨论了 RTF 与真实硬件的集成。该论文的作者开发了软件，包括 CAEN DT5742 数字化仪的 RTF 功能块、示例数据处理算法、等离子控制系统的数据归档和发布。本文提出了一个完整的数据采集和处理系统，专用于基于 ITER 实时框架 (RTF) 的等离子体诊断。讨论了 RTF 与真实硬件的集成。该论文的作者开发了软件，包括 CAEN DT5742 数字化仪的 RTF 功能块、示例数据处理算法、等离子控制系统的数据归档和发布。本文提出了一个完整的数据采集和处理系统，专用于基于 ITER 实时框架 (RTF) 的等离子体诊断。讨论了 RTF 与真实硬件的集成。该论文的作者开发了软件，包括 CAEN DT5742 数字化仪的 RTF 功能块、示例数据处理算法、等离子控制系统的数据归档和发布。
