A detection efficiency of a flared-type micro channelplate (70% open surface area) was measured using the time-of-flight atom-probe which had an 100% detection efficiency. The efficiency was found to be 66 + 7%, higher than that( approximately 60% ) of a regular channelplate, but not as high as that expected from the increased aperture size.
