Abstract (en)
[origin: WO2014146673A1] An electron multiplier assembly comprises a first electrode plate supported on a second electrode plate by a means of plurality of spacers. Through-holes are formed in the first electrode plate and in the second electrode plate and are carefully aligned so to form amplification channels in the gap between the first electrode plate and the second electrode plate. The amplification channels allow to convert primary electrons into an avalanche of electrons that may be detected with suitable readout means. The detector structure is wall-less in the sense that neighboring amplification channels are not separated by walls, which allows to reduce leakage currents and to provide a detector that can be used with a plurality of detector gases or even in humid ambient air.
