摘要:

使用一维数值模型, 推断了逃逸能量εr与逃逸约束时间τr的关系。模拟结果给出能量εr 和放电参数的定标律。在HL- 1M 装置中不同实验条件下测量了硬X 射线谱, 研究了逃逸电子能量 εr模拟的定标律, 并推导出HL- 1M 装置放电的逃逸电子的约束时间与逃逸电子扩散系数。

关键词: 逃逸电子能量, 逃逸电子约束时间, 逃逸扩散系数, 硬X 射线谱

Abstract:

Runaway confinement time in ohmic and additionally heated tokamak plasmas presents an anomalous behavior in comparison with theoret ical predictions based on neoclassical models. A one-dimensional numerical including generat ion and loss effects for runaway electrons is used to deduce the dependence of runaway energy  εr on runaway confinement time. The simulation results are presented in the form of a scaling law for εr on plasma parameters. The scaling of εr and therefore the runaway confinement t ime and runaway electron diffusivity has been studied in the HL-1M tokamak, by measuring hard X-ray spectra under different experimental condit ions.

Key words: Runaway energy, Runaway confinement time, Runaway electron diffusivity, Hard X-ray spectra
