A study of the triggered plasma opening switch characteristics is in progress via an ion current collection diagnostic (ICCD) in addition to an offline apparatus. The ICCD will be used to explore the opening profile of the plasma opening switch. The design and fabrication of the diagnostic, as well as theoretical work to understand its functioning, and the initial measurements are presented. The ICCD...
Summary form only given. The plasma formation and implosion characteristics, as well as the energy in X-ray radiation, from two and multiwire X pinches have been investigated and compared using the XP and COBRA pulsed power generators at Cornell University. The XP generator (40-50 ns rise time, 450 kA peak current) has been used for the X pinch studies and applications for several years. The rebuilt...
Summary form only given. The X pinch has proven itself to be both an extraordinary X-ray back lighting source and an interesting high energy density plasma for plasma dynamics and X-ray spectroscopy studies. However, some of the most interesting physics of an X pinch happens on a few ns, or even subnanosecond, time scale. The X pinch has been estimated to approach solid density on a size scale of...
The Triggered Plasma Opening Switch (TPOS) at SNL is a unique device that exploits the high conductivity and low mass properties of plasma. The TPOS's objective is to take the initial ~0.8 MA (~250 ns rise time) storage inductor current and deliver ~0.5 MA at ~2.4 MV (~10 ns rise time) to a load of ~5-10 Omega. Configuration advantages include low current jitter and resistive voltage drop, power gain,...
