Eight-channel disk amplifiers of the ISKRA-6 facility are made up of sections. An amplifier section consists of eight active elements ($2\times 4$) made of KGSS 0180/35-grade neodymium phosphate glass $400\times 690\times 40\,{\rm mm}$ in size located in frames at the Brewster angle. Twenty flashlamps are arranged in one amplifier module. The flashlamps have an inter electrode distance of 1600 mm, the tube is 40 mm in inner diameter. There are presents the results of numerical investigations into the dynamics of high-current pulse radiation discharge. The investigations were carried out by the RMHD-model. The experimental results of spectral measurements and light efficiency of the flashlamps depending on specific power and value of energy contribution are presented.
