ABSTRACT:
Shock resistant microchannel plate assemblies incorporating stacked or cascaded microchannel plates, and to methods of their use are disclosed. High-output amplification tubes of the photomultiplier type, or of the image intensifier type, having a plurality of sequentially arranged, or cascaded, electron multiplier microchannel plates are also disclosed. More particularly the present invention relates to a high output photomultiplier tube or image tube having cascaded microchannel plates radially constrained by an annular insulating ring. In another aspect of the present invention image intensifier tubes or photomultiplier tubes may include a tapered ceramic high voltage stand-off. Moreover, a method of making such tubes is also disclosed.
