Title: Technique for insulated and non-insulated metal liner X-pinch radiography on a 1 MA pulsed power machine

Abstract

Broadband, high resolution X-pinch radiography has been demonstrated as a method to view the instability induced small scale structure that develops in near solid density regions of both insulated and non-insulated cylindrical metallic liners. In experiments carried out on a 1-1.2 MA 100-200 ns rise time pulsed power generator, μm scale features were imaged in initially 16 μm thick Al foil cylindrical liners. Better resolution and contrast were obtained using an X-ray sensitive film than with image plate detectors because of the properties of the X-pinch X-ray source. Here, we also discuss configuration variations that were made to the simple cylindrical liner geometry that appeared to maintain validity of the small-scale structure measurements while improving measurement quality.

There is a 4-wire 25 μm Mo X-pinch positioned in placemore » of one of the return current posts. The second return current post is positioned radially farther out than the X-pinch in order to increase its relative current path inductance. The anode is held in place by the white plastic supports.
