Analysis and Tests of a 90-cm Right Circular Cylinder in the PIMBS 1A Photon Environment.

Abstract

An initial analysis verification experiment is described, based on a 90-cm right circular cylinder exposed to low-level, low-frequency, 75-keV bremsstrahlung, x-ray source. Pretest analytical predictions of several surface H fields on the cylinder were made using QUICKE2 to calculate the electron emission from the object, for the expected photon pulse, and the 2D particle code ABORC. These were then compared to the experimental results and found to be higher by a factor of 2.6 (+0.6 or -0.7). This is believed to result from emission that was a factor of about 2 lower than expected, as measured in a separate biased x-ray diode experiment.
