ABSTRACT:
A microchannel plate (P) for receiving photoelectrons includes a plate-like substrate web (W) formed from a plurality of micro-tubules (10) of a single type of cladding glass (12) and defining a pair of opposite faces (14aand14b). The substrate web (W) further includes a plurality of microchannel passages (16) extending between the opposite faces (14aand14b) and having openings (18aand18b, respectively) in both of the opposite faces (14aand14b). The microchannel openings (18) have funnel-like entries or openings (20) formed in the substrate web (W) with at least one of the opposite faces (14).
