Microchannel plates are widely used today in military night vision devices. Their successful application has prompted widespread interest in many laboratories and in the industry for use in diagnostic tools. Of particular interest are the applications as: (a) an electro-optical ion detector to enhance the sensitivity of a mass spectrometer for clinical environment and chemical analysis, (b) an electron collimator for subpicosecond x-ray and visible streak camera tubes, and (c) particle detectors in spaceborne instrumentation. Many of these applications required the development of strip multichannel arrays (SMCA) ranging in active area from 1 mm x 15 mm up to 1 mm x 360 mm. Also described herein is the state of the art of high resolution and increased detection efficiency multichannel arrays.
