Abstract :
Summary form only given. Since 2000 year LUCH laser facility has been worked at RFNC-VNIIEF. This facility was designed as prototype of ISKRA-6 128-beams facility that is developing now. Basis of LUCH facility is 4-beams Nd-glass laser with operating aperture 20times20 cm. This laser is included two four-path amplifiers that are pumped by 432 xenon flashlamps. The capacitor bank with near 5MJ stored energy at operating voltage of 24 kV has been constructed to drive amplifiers flashlamps. 18 unified modules are included in the bank. Each single module is discharged to lamp load by semiconductor closing switch based on reverse switched dynistors. Description of module components and bank subsystems such as charging, triggering, control and diagnostic is presented in this report. Also the bank performance during the exploitation is discussed.
