PLASMA OPTICAL RADIATION SOURCE Russian patent published in 2012 - IPC H05H1/16 

FIELD: physics.

SUBSTANCE: plasma optical radiation source, having a power supply in form of a thyristor rectifier and a radiating plasma generator from a discharge unit and a unit for generating a clamping magnetic field in form of an electromagnet, wherein the discharge unit is in form of tray placed in the gap of the core of the electromagnet, said tray being made from dielectric material and coated with heat resistant material based on compounds of easily ionisable elements and having a flat bottom and through holes on the side walls, in the open ends of which there are graphite electrodes; the source further includes a second power supply in form of a high-voltage storage capacitor, a drive-pulse generator, a controlled discharger and a third electrode made from refractory material, placed between the end electrodes and connected through the controlled discharger to the positive lead of the storage capacitor, wherein the earthed leads of the thyristor rectifier and the high-voltage storage capacitor are connected to one of the end electrodes of the discharge unit, the positive lead of the thyristor rectifier is connected to the second end electrode, and the third electrode and earthed end electrode are connected to a discharge initiator and the drive-pulse generator is connected to the controlled discharger and the thyristor rectifier.

EFFECT: design of a highly efficient universal plasma radiator which can operate in pulsed mode with high brightness, in quasi-continuous mode with high radiation energy, as well as in a combined mode which produces an irregular light pulse shape with high peak brightness, high radiation energy and considerable surface area of the radiating surface.
