MICROCHANNEL PLATE HAVING INPUT/OUTPUT FACE FUNNELING

摘要

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 ( 14 a and 14 b). The substrate web (W) further includes a plurality of microchannel passages ( 16 ) extending between the opposite faces ( 14 a and 14 b) and having openings ( 18 a and 18 b, respectively) in both of the opposite faces ( 14 a and 14 b). 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 ).
