Abstract

The now-mature FXR (flash X-ray) radiographic facility at Lawrence Livermore National Laboratory will be briefly described with emphasis on its pulsed power system. The heart of each accelerating cell´s pulse-forming Blumlein is its sulfur hexafluoride-based triggered closing switch. FXR´s recent upgrade to a recirculating SF₆ gas reclamation system will be described and the resulting accelerator performance and reliability improvements documented. This was accompanied by a detailed switch breakdown study on FXR´s test stand and the recent analysis of the resulting statistics will be shown.
