Measurement of energy deposited by charged particle beams in composite targets. [0. 5 to 28. 5 GeV]
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 /sup 238/U shower plates backed by a composite detector plate consisting of a 5-cm-thick CH/sub 2/ moderator and a 0.635-cm /sup 238/U 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 /sup 238/U 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/cm/sup 2/). 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.
