This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The energies deposited in composite targets by proton beams from 0.8 to 28.5 GeV energy and by an electron beam at 0.5 GeV energy were measured. The targets consisted of various thicknesses of 238U shower plates backed by a composite detector plate consisting of a 5-cm-thick CH2 moderator and a 0.635-cm 238U plate. The spacing between the shower and detector plates was varied to allow different spreading of the shower between plates. Passive detectors (thermoluminescence dosimeters, Lexan fission track recorders, photographic emulsions, and removable 238U pieces) were used to measure the fission-fragment dose and the nonfission dose at various depths and radial positions in the targets. Plots and numerical values of the measured doses are presented for comparison with computer code calculations. To provide a basis for comparison of the effects of different particle beam energies, data along the beam axes are presented as specific dose (cal/g per incident integrated kJ/cm2). In general, the higher the incident proton energy, the larger is the dose in the back of the target relative to that in the front.
