Measurementshave been made of the 0" bremsstrahlung spectrum emerging from thick targets of polystyrene, aluminum, coppcr, 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(T1) 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 curvcs of number of photons per mega-electron volt per microampere pcr steradian at zero degrees vs. photon energy. Comparisons are made with some elementary semi-empirical prcdictions of thick target bremsstrahlung spectrum shapes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
