J. Villette et al., Calibration of a multiple microchannel plate detectors system by alpha-induced secondary electrons, REV SCI INS, 71(6), 2000, pp. 2367-2370
alpha particles emitted from an Am-241 radioactive source at energies of 5.
4 MeV generate bursts of about ten electrons when passing through an alumin
ized Mylar foil. Besides the typical surface barrier electrons, the energy
spectra of the secondary electrons clearly reveal two additional peaks. One
at 66 eV is ascribed to aluminum LVV Auger electrons and another at 10.5 e
V is attributed to the decay of aluminum volume plasmons. The well-resolved
angular and energy distributions of these secondary electrons are used to
calibrate the relative detection efficiencies of a large set of individual
detectors of a complex multicoincidence system. (C) 2000 American Institute
