摘要：

The experiments on electron-cyclotron resonance heating (ECRH) of plasma in the L-2M stellarator were carried out in a regime with reduced radiative losses, under improved boundary conditions achieved by vacuum chamber boronization. L-2M is a classical two-pole stellarator ( l = 2, m = 7) with a large shear. The major radius is R = 1 m, the minor plasma radius is a = 0.115 m, the toroidal magnetic field is 1.34 T, and the rotational transform varies from. iota( 0) = 0.176 at the magnetic axis to. iota(a) = 0.78 at the plasma boundary. The magnetic surfaces are elliptical [1]. The main method for plasma heating is X-mode ECRH at the second harmonic of the electron gyrofrequency. The power sources are 75-GHz gyrotrons. The microwave Gaussian beam is focused onto the stellarator axis ( R = 0.975 m).
