Plasma parameters of an electron cyclotron resonance discharge in a magnetic mirror in a quasi-gasdynamic confinement regime

An experimental investigation is made of x-ray bremsstrahlung in the 2-10 k eV range of a pulsed discharge under electron cyclotron resonance condition s in a straight magnetic mirror system pumped by a high-power millimeter ra diation beam. The plasma temperature and density were determined from the s pectrum and intensity of the x-rays. The results indicate that a quasi-gasd ynamic plasma confinement regime is achieved.
