Abstract

An overview is given of SPARC's three main x-ray diagnostics, with a focus on the functions they fulfill with respect to tokamak operation. The first is an in-vessel soft x-ray tomography diagnostic, aimed at providing early campaign information on plasma position, MHD activity, and impurity content. The second is an ex-vessel set of hard x-ray scintillators aimed at detecting the presence of runaway electrons, in particular during plasma startup phases. The third is a set of x-ray Bragg spectrometers, located outside of the tokamak hall, aimed at informing on the ion temperature as an indirect constraint to reduce uncertainties on the fusion power, on providing plasma rotation velocity estimates, and on observing impurity emission. Finally, more technical details are given on the beamlines at the end of which the spectrometers are located. It explains how their design allows us to ensure tritium containment and limit neutron radiation while providing a straight view into the plasma that can also be used for testing new innovative sensors.

SPARC X 射线诊断仪：技术和功能概览

本文概述了 SPARC 的三种主要 X 射线诊断方法，重点介绍了它们在托卡马克运行方面的功能。第一种是舱内软 X 射线断层扫描诊断，旨在提供有关等离子体位置、MHD 活动和杂质含量的早期活动信息。第二种是舱外硬 X 射线闪烁器，旨在探测失控电子的存在，特别是在等离子体启动阶段。第三套是位于托卡马克大厅外的一套 X 射线布拉格光谱仪，旨在提供离子温度信息，作为减少聚变功率不确定性的间接约束条件，提供等离子体旋转速度估计值，并观测杂质发射。最后，详细介绍了位于光谱仪末端的光束线的技术细节。报告解释了它们的设计如何使我们能够确保氚的封闭性并限制中子辐射，同时提供一个直视等离子体的视角，该视角还可用于测试新的创新传感器。
