Note: Absolute detection efficiency of a tapered microchannel plate for Ne+ ions

The absolute detection efficiency of a tapered microchannel plate with an open-area ratio of 90% was measured for Ne+ with energies up to 5 keV, and comparison with the results for Xe+ was made. As in the case of Xe+, the maximum detection efficiency was 90%. The energy dependence of the efficiency curves normalized with respect to the open-area ratios was examined based on the scaling law proposed previously.
