Quasi-continuous source of radiation on the basis of a magnetically fixed discharge

Abstract

A quasi-continuous mode of operation is realized for a plasma source of light utilizing a magnetically fixed discharge with the glow duration of 0.2 s. It is demonstrated that, with a discharge channel length of 8 cm and width of 2 cm, a magnetically fixed discharge with a magnet system in the form of an electromagnet with transverse magnetic field induction of 4.5 × 105 A/m at a current of 5000 A provides a radiation power of 80 kW. During the time of glow, the plasma source radiates 17.5 kJ. The spectral distribution of radiation energy is close to that of blackbody at T = 5500 K.
