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

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 $4.5 \times 10^5$ 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.
