Determinations of plasma parameters as well as the Magnetohydrodynamics (MHD) activity, energetic electrons energy and energy confinement time are essential for future fusion reactors experiments and optimized operation. Also some of the plasma information can be deduced from these parameters, such as plasma equilibrium, stability, and MHD instabilities. In this contribution we investigated the relation between energetic electrons, hard x-ray emission and MHD activity in the IR-T1 Tokamak. For this purpose we used the magnetic diagnostics and a hard x-ray spectroscopy in IR-T1 tokamak. A hard x-ray emission is produced by collision of the runaway electrons with the plasma particles or limiters. The mean energy was calculated from the slope of the energy spectrum of hard x-ray photons.
确定等离子体参数以及磁流体动力学（MHD）活动、高能电子能量和能量约束时间对于未来聚变反应堆实验和优化运行至关重要。此外，一些等离子体信息可以从这些参数中推导出来，例如等离子体平衡、稳定性和MHD不稳定性。在本论文中，我们研究了IR-T1托卡马克中高能电子、硬X射线发射和MHD活动之间的关系。为此，我们在IR-T1托卡马克中使用了磁诊断和硬X射线光谱学。硬X射线发射是由逃逸电子与等离子体粒子或限制器碰撞产生的。平均能量是根据硬X射线光子能谱的斜率计算出来的。
