    Abstract

    Making use of a technique of layer-by-layer field evaporation developed in the time-of-flight atom probe, the detection efficiency of a microchannelplate supplied by Galileo Electro Optics is determined. The detection efficiency for single ion impact is 57 ± 8%, close to the fraction of the active channel area of the surface. It increases slightly, but no more than a few percent, even the front surface is positively biased.
