Abstract:
A micro random channel plate device suitable for use in an electron multiplier, comprising:a substrate having on at least one surface thereof a performing substance layer of 10 .mu.m to 3000 .mu.m thickness comprising a plurality of randomly situated randomly orientated crystallite dynodes having interspersed therebetween a plurality of random microchannels, said microchannels composed of open space, the average electron track length L of said microchannels being greater than 2 .mu.m and less than said thickness of said performing substance layer, said microchannel plate device having a gain in excess of 10.sup.4, and a dark current less than 0.2 sec.sup.-1 cm.sup.-2, wherein said performing substance layer has a density of from 0.3% to about 4% of the density of the performing substance when in a monocrystalline state.
