“…The method for determining plasma density and temperature is based on recording and analyzing the spectrum of the bremsstrahlung radiation emitted by free-free transitions of electrons in the electric field of ions. Assuming a model function of the electron energy distribution, the electron temperature can be determined from the slope of the spectrum on a semi-logarithmic scale, and the absolute value of the x-ray intensity can be used to estimate the particle density [22][23][24]. To facilitate diagnostics of plasma parameters inside the magnetic trap, two 10 mm diameter flanges with CF40 flanges in the center of the discharge chamber were used.…”

Plasma of a stationary ECR discharge sustained by gyrotron radiation at a frequency of 24 GHz and a power of up to 600 W in a mirror magnetic trap was studied. At pressures near the gas breakdown threshold, the extinction effect of an electron-cyclotron discharge is observed with increasing radiation power. When the cyclotron resonance cross section approaches the magnetic plug, the power threshold corresponding to the discharge extinction decreases. These experimental results confirm the presence of the effect of particles precipitation from the trap as a result of electroncyclotron resonance interaction with gyrotron radiation. The experimental scaling of the extinction power dependence on the position of the ECR cross section in a magnetic trap corresponds to the results of the estimates on the basis of the theory of particle precipitation in the quasilinear diffusion regime.
