Abstract : The design, development, and testing of a spaceflight experiment to provide data for the assessment of mathematical shielding study models was investigated. The experiment was to provide data for assessment of mathematical shielding study models for comparison with the results obtained by a computer program. This experiment measured proton depth-dose distribution, bremsstrahlung production, and the effects of radiation anisotropy, energy spectrum, and vehicle heterogeneity under known (measured) conditions of radiation environment and vehicle geometry. The experiment instrumentation included sensors for measurement of proton and electron fluxes and spectra, and sensors to measure dosage under various shielding thicknesses of aluminum. An instrument to measure x-ray bremsstrahlung from incident electron flux was also provided. The instrument design features are discussed and methods of operation described. (Author)
