Ionizing Radiation Dose Distribution Produced inside a Canonical Cavity by Direct e-Beam Excitation

Reliable dosimetry methods have been developed to map relativistic electrons that have been injected into a generic cavity. These measuring techniques are: (1) thermoluminescent dosimeters (TLDs) combined with photodiodes yielding dose rate; (2) TLD telescopes yielding electron angular distributions; and (3) TLD mosaic arrays yielding rough energy spectra. Total dose, dose rate, electron angular distribution and current density measurements have been obtained during electromagnetic excitation of a canonical cavity with diffuse electron beam (e-beam) bombardment. A theoretical interpretation of the dose rate and electron current density measurements is presented.
