The radiation and energy contribution of a pulse-periodic discharge in helium

An experimental investigation is performed of the energy contribution and r adiation of a pulse-periodic discharge in the form of a high-velocity ioniz ation wave in helium with the pulse voltage amplitude of 14-18 kV, the dura tion at half-height of 77 +/- 2 ns, the front of 19 +/- 2 ns, and the repet ition rate of 1200 Hz. It is found that, under certain conditions, a more e fficient energy contribution is made by pulses reflected back from the gene rator.
