A new multistage gas switch (Rimfire) has been developed for 6 MV operation in the PBFA-II ion beam accelerator. This gas switch has demonstrated good high voltage survivability and has been successfully triggered by the KrF laser beam at 248 nm with less than 30 mJ of energy. These laser triggered switching (LTS) experiments at approx. 5 MV have achieved controlled switching having subnanosecond jitter and switch closure delay dependence upon charging voltage exhibiting slope less than 1 ns for a 1% voltage change relative to the self-breakdown voltage (SBV).
