Publication Detail
Detection of low-energy charged particles by channel electron multipliers
Abstract
Experimental determinations of the detection efficiency for positrons impacting a channel electron multiplier with incident energies between 0−1400 eV are presented. A log-normal dependence with energy is established and used to compute the positron-to-positronium detection efficiency ratio as a function of positronium energy, as required for determining quantities involving the ratio of positron and positronium rates. A log-normal energy-dependence is also observed in results of previous work with electrons, protons and ions.
