ABSTRACT:
A linear array of electron multiplier microchannels is formed by fusing a plurality of solid core glass fibers into a rectangular array. A number of arrays is then sandwiched between a pair of glass plate support members fused into a linear arrangement followed by treating to form the electron multiplier. Treatment comprises subjecting the arrangement to an acid etch for removing the core material and hydrogen firing to activate the core walls for secondary electron emission. The apparatus finds application as an ion-electron converter in focal plane mass spectrometers where high electron gain is required.
