Protection of control and monitoring equipment from electromagnetic noise in the 67MJ, 50kV capacitor bank

A discharge of the 67MJ and 50kV capacitor bank used as a pulsed power system for flashlamp pumping of ISKRA-5´s high-power iodine laser, involves control and diagnostic equipment being subjected to significant electromagnetic fields and electrical interference that will further develop through conductive circuits. The paper describes and validates design approaches to the grounding system, signal carriage and decoupling circuits that would result in lower interference both for the capacitor bank´s control and diagnostics systems. A summary is also given of the ten-years´ practice in operating the control and diagnostics equipment during the facility experiments.
