摘要：

Erosion of POCO graphite by helium in PISCES-A was measured by carbon spectroscopy at temperatures from 550-degrees-2000-degrees-C, energies of 30-250 eV and fluxes of 1-2 X 10(22) m-2 s-1, Yields at low energies were higher than predicted in current models. The effect of redeposition is discussed.
