Measurement of trigger and cascade section runtimes in 6 MV switches using fiber coupled photodetectors

Measurement of trigger and cascade section runtimes in 6 MV switches using fiber coupled photodetectors

Since October 2007 Sandia National Laboratories has operated the refurbished Z machine at an improved load current of 26 MA yielding 400 TW of x-ray power. The current pulse shape to the load is controlled by 36 independently timed laser triggered gas switches. As part of the refurbishment effort, a...
