Diagnostics have been developed for use on superpower generators with fast Z-pinch loads and are used to characterize the electrical power flow and the imploding plasma load. X-ray diagnostics include both grazing incidence grating and crystal spectrographs, an X-ray framing camera, arrays of bare and filtered X-ray diodes, calorimeters, and ruby laser holographic interferometry. Plans include an...
We describe a current viewing resistor {CVR) which measures current in magnetically insulated feeds (MITLs) of pulsed power accelerators. The advantage of a CVR for this application is that, by keeping the feed geometry smooth, it does not disturb the electron space-charge flow in the gap. In this paper we review the transient behavior of CVRs associated with diffusion of magnetic field in the sensing...
EAGLE is an experimental pulse generator designed and built at Physics International Company (PI) for research in high-power switching, pulse compression, power flow, magnetic insulation, and dielectric breakdown. EAGLE is a wedge-shaped 1/20th "slice" (module) of ROULETTE, Pi's conceptual design for a 40 to 50 TW, disk-shaped, modular accelerator designed to drive imploded plasma or particle...
We report on the development of a water vacuum interface for the EAGLE facility at Physics International Company. An interesting feature of this insulator is its construction-cast urethane is bonded directly to metal to form a vacuum seal. We report on the mechanical process development, design considerations for EAGLE, and results from experiments on a half-scale prototype.
Magnetically insulated vacuum feeds have been investigated for use in an electron beam fusion accelerator. The magnetically insulated transmission lines would transfer the power pulses from many accelerator modules to a single diode region or multiple diodes to generate currents of the order of 100 MA. This approach may allow the present limits on power flow through dielectric/vacuum interfaces to...
