摘要：
Rates of erosion of neutron-producing targets at the ISIS Spallation Neutron and Muon Source are deduced on the basis of gamma-ray spectrometry. The results suggest that for TS-1 targets erosion rates decrease with time, whereas erosion rates for TS-2 targets increase with time. Absolute masses eroded over typical target lifetimes are several milligrams of tantalum for TS-1 targets, and -1 g of tungsten for TS-2 targets.
