METHOD OF PLASMA OPTICAL RADIATION SOURCE PRODUCING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC H05H1/50 

FIELD: electrical engineering.

SUBSTANCE: invention relates to plasma engineering, particularly to methods and devices with emitting plasma, and can be used to solve wide range of technical tasks, for example when testing instruments and materials for resistance to radiation by light radiation, similar to natural and technogenic factors radiation. Method of producing plasma optical radiation source based on erosion type magneto pressed arc discharge by forming in interelectrode gap after establishing in it preset value of magnetic field of continuous and pulsed discharges with time interval between them, new feature is that, at specified value of magnetic field value of arc discharge burning minimum voltage is determined and arc discharge current corresponding to this voltage, value of time interval between formation of continuous and pulsed discharges is found from set ratio, sequence of formation of continuous and pulsed discharges is defined by sign of determined time interval: with positive sign first generated is continuous discharge, otherwise is pulse discharge, with zero value of time interval formation of discharges is started simultaneously, wherein formation of continuous discharge is carried out at voltage at its power supply source output of not less than arc discharge burning voltage, and total current of pulsed and continuous discharges is maintained at level of not less than arc discharge current corresponding to arc discharge burning minimum voltage. Invention also covers light radiation plasma source, including radiating plasma generator, implementing method.

EFFECT: technical result is expansion of functional capabilities, obtaining powerful light radiations, similar by time form to man-made and natural light radiations, while maintaining high reliability of their operation.
