Abstract

The magnetic pulse compressor is intended for pumping the excixner discharge laser (EDL) with a mean radiation power of 1 kW and pulse repetition frequency as high as 200 Hz. The compressor is formed by the input stage, consisting of four parallel capasitor chains to double the voltage in Fitch sceme, commutated by thyratrons, and one magnetic compression stage. The saturating chouke of the stage has one turn on the oval core the external dimensions of which are 800 cm x 350 cm and cross-section is 120 cm². The core is made of a 25 μm thick metal amorphous tape 2HCP. The compression stage capacitance is of 120 nF, maximum thyratron charge voltage of 50 kV, voltage amplitude at the laser discharge gap of 60 kV arid voltage rise time of 120 ns. At present XeCl laser radiates energy pulses of 3 J at the frequence of 200 Hz. In future the switches having charging voltage of 70 kV are supposed to be installed and thus I kW radiation power to be obtained.
