Abstract
The absolute values of the efficiency of detection of Cs+ and Cl- ions with energies of 1600 eV have been measured with a ВЭУ-7-2 microchannel electron multiplier. The relative detection efficiencies as functions of the potential of the input surface of the microchannel plate have been assessed. It has been revealed that the absolute values of the efficiency of detection of Cl- and Cs+ ions differ significantly and amount to 36 and 6%, respectively, at input ion currents of ≤2 × 10−14 A.
