Notes:
The detection efficiencies of parallel-plate electron multipliers with a parallel electric field (PPEM-parallel) and with a tilted electric field (PPEM-tilt) have been calculated by a Monte Carlo simulation method. The detection efficiencies vary with the geometrical conditions of the dynodes such as the dynode spacing, the dynode displacement, and the dynode length. Under the optimum geometrical conditions that give the maximum mean gains, the PPEM-parallels have a detection efficiency of 75% and the PPEM-tilts have a detection efficiency of 70% for an incident electron energy of 300 eV. These values do not vary with the applied voltage. Detection efficiency versus incident electron energy curves has been obtained for the optimum geometrical conditions. The forms of these curves are almost the same for the PPEM-parallel and the PPEM-tilt and do not change with the applied voltage. © 1995 American Institute of Physics.
