Abstract

The paper summarizes the actions taken to make safer the operation of the ignitron main crowbar system used to protect the winding and the power supplies forming the circuit which produces the toroidal magnetic field for plasma confinement in the RFX machine. Such actions, which comprise a self-triggering system, a monitoring system and a discharge resistors system, are intended to minimise the probability of explosion of the crowbar ignitrons in case of misfiring and to maintain a high level of reliability for the crowbar system operation
