Measurements have been made of the 00 bremsstrahlung spectrum emerging from thick targets of polystyrene, aluminum, copper, silver and gold bombarded by monoenergetic electrons of 1.0 MeV, 1.5 MeV and 2.0 MeV. The measurements were made using a 4 in. diameter by 4 in. long NaI(Tl) scintillation detector unit with a lead shield and collimator. The pulse-height spectra were recorded in a twenty-channel, pulse-height analyzer and were converted to photon spectra using an experimentally determined response matrix for the scintillation detector. Corrections and errors arc discussed and the results are plotted as families of curves of number of photons per mega-electron volt per microampere per steradian at zero degrees vs. photon energy. Comparisons are made with some elementary semi-empirical predictions of thick target bremsstrahlung spectrum shapes.
