摘要：

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.
