Soft X-ray spectra coming from the ECR heating region, non-distorted by the effect of the plasma-wall interaction, are measured at the L-2M stellarator in experiments on axial and off-axial ECR heating. In both cases, the measured soft X-ray spectra turned out to be non-Maxwellian. It was found that the electrons forming the suprathermal spectral region are produced in the heating region, but do not come from the plasma-wall interaction region.

L-2M恒星发生器在ECR加热区中的软X射线光谱的测量以及超热电子的局域化区域的确定

在轴向和离轴ECR加热实验中，在L-2M恒星仪上测量了来自ECR加热区域的软X射线光谱，该光谱未受等离子-壁相互作用的影响而失真。在这两种情况下，所测得的软X射线光谱均为非麦克斯韦光谱。发现形成超热光谱区的电子在加热区中产生，但不是来自等离子体-壁相互作用区。
