Abstract:

A time-resolved pinhole camera has been constructed to diagnose the x-ray emitting source of the SATURN accelerator. The detector for the camera is a 20-channel, linear array of plastic scintillators, placed beneath adjustable jaws optical signals are connected by fiber-optic links to a remote bank of photomultiplier PM tubes. Variations in the channel-to-channel response have been reduced by exposing the complete array to a nearly uniform pulsed x-ray field Febetron 706, e-beam tube with Ta converter and adjusting the gains on the PM tubes. Experiments under SATURN to date have yielded information on the simultaneity of the source rings, x-ray pulse widths, and the duration of hot spots. The camera complements existing diagnostics, such as time-integrated and multiframe, gated cameras and non-spatially resolved PIN and scintillator-photodiode detectors.
