- 論文の詳細を見る
We developed a microchannel plate (MCP) with tapered micropores that form a large effective open-area ratio (90%). The absolute detection efficiencies of conventional and tapered MCPs were measured for singly and multiply charged Xe ions at incident energies between 0.5 and 13.5 keV. Asymptotic values of the absolute detection efficiencies for the conventional and tapered MCPs were 65% and 88%, respectively. These values are nearly equal to the open-area ratios, indicating the MCPs with even higher detection efficiency can be developed.
