Response of a Fermilab-Designed Ion Chamber in Pulsed Photon Fields

摘要

This note reports measurements of the response of a Fermilab-designed area monitor ionization chamber used in Chipmunk and Scarecrow detectors to pulsed photon fields of various intensities and durations. The measurements were made to better define the operating limits of the instruments and to understand the possible effects of recombination and space charge on the dose measured by the instruments in pulsed fields. 2 refs., 13 figs., 1 tab.
