We are investigating several techniques to obtain time-dependent magnetic field measurements in wire-array Z-pinches and X-pinches. One general approach is to use “remote sensing” methods whereby a very small sensor material is placed in the plasma and then is investigated to extract useful information. Faraday rotation of polarized laser light traversing a small area through thin film waveguides coupled to a fine optical fiber is a possibility. While these films may not survive for long in a dense Z-pinch, they may provide useful information for a significant fraction of the current pulse. We also discuss results of experiments conducted using magnetic CoPt thin films to obtain the maximum magnetic field seen by the film near the end of the load current pulse. © 2006 American Institute of Physics

    Imaging using X-pinch backlighters has been implemented on the COBRA accelerator at Cornell University to study the early stages of wire-array Z-pinches. Two of four return-current posts in the wire-array load region are replaced by X pinches so that two images of one wire in an eight-wire...
