Abstract

A review of various mechanisms of suprathermal electron generation in tokamak plasma and an analysis of diagnostic systems for the study of the spatial evolution of electron beams are presented. It is planned to use detectors based on CdTe crystals to detect suprathermal x-ray emission (20–300 keV) at the T-15MD tokamak (R = 1.5 m, a = 0.67 m). Spatial resolution is provided by a system of tube collimators placed in detector chambers mounted in vertical, inclined, and equatorial diagnostic ports. To measure suprathermal x-ray emission spectrum, a set of CdTe spectrometric detectors and LaBr₃(Ce) scintillation crystal detectors are used. The tomographic program is used to reconstruct spatial localization of the X-ray emission. The received spatial and temporal distribution of local suprathermal electron beams will be used to study a variety of physical phenomena, such as reconnection of magnetic field lines, nonlinear transport processes, distortion of the electron energy distribution function during powerful additional heating and current drive, and plasma perturbances that are important for the study of kinetic instabilities in plasma with fast ions.

T-15MD托卡马克上超热x射线辐射的层析成像诊断

本文综述了托卡马克等离子体中超热电子产生的各种机制，并分析了用于研究电子束空间演化的诊断系统。计划使用基于CdTe晶体的探测器来探测T-15MD托卡马克（R = 1.5 m, a = 0.67 m）上的过热x射线发射（20-300 keV）。空间分辨率由放置在垂直、倾斜和赤道诊断端口的探测器室中的管状准直器系统提供。采用一套CdTe光谱探测器和LaBr3（Ce）闪烁晶体探测器来测量超热x射线发射光谱。层析程序用于重建x射线发射的空间定位。接收到的局部超热电子束的时空分布将用于研究各种物理现象，如磁力线重联、非线性输运过程、在强大的附加加热和电流驱动过程中电子能量分布函数的畸变，以及对研究具有快离子的等离子体动力学不稳定性很重要的等离子体扰动。
