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 2 Piece Power Reclining Sofa Console effort, a fiber coupled laser spark detector system has been installed which is able to detect the laser generated plasma in situ inside the trigger section of the high voltage switch.

In this paper we describe how this FERMENTED WHEATGRASS detection system can be used to characterize the discharge dynamics of these 5.9 MV, 820 kA switches.
