The AURORA bremsstrahlung environment

This report compiles all measurements and calculations characterizing the bremsstrahlung output of AURORA. The first part gives measurements of the dose distribution throughout the test cell and on the anode faceplates. All dose maps are given in normalized form so that the dose and the dose rate may easily be found for any Marx charging voltage. The second part describes the measured time history of the bremsstrahlung pulse from early times to very late times over four decades of amplitude. The third part discusses the bremsstrahlung energy spectrum and presents calculations of the energy and the angular distribution of photons. It is hoped that this report will be useful to prospective experimenters planning tests at the AURORA Facility.
