Title: Absolute calibration of a prompt gamma ray detector for intense bursts of protons

Technical Report ·
OSTI ID:5466132

A detector for determining the itensity and duration of kiloampere pulsed proton beams is described. Proton intensities are inferred from measurements of prompt gamma rays of 6 to 7 MeV from the /sup 19/F(p,a..gamma..)/sup 16/O reaction. The thick-target yield for this reaction on a teflon target was measured for 0.5 to 2.8 MeV protons. Two different size detectors were calibrated absolutely using the continuous proton beam from a Van de Graaff accelerator. An absolute measurement of a kiloampere pulsed proton beam is described, and the measured current is in agreement with an independent determination of the total proton intensity by nuclear activation.
