Summary

Low-energy and high-energy electron yields have been measured from Al, Cu, Ta, and Pb targets bombarded by 0.2 MeV to 1.4 MeV electrons. An improved apparatus, the hemispherical triode, is shown to be very effective in measuring the total yield of high-energy electrons (= or> 100 eV) and the total yield of low-energy electrons (<100 eV). The low-energy yields measured with the hemispherical triode are significantly less than the low-energy yields previously reported in the literature. The reasons for the improvement in data are discussed and experimentally verified. The improved data can be used to determine the energy deposition at the surface of the metal targets. The data also shows a strong dependence on the target surface texture; this dependence is briefly studied. (Author).
