Title:
MICRO-CHANNEL PLATE
Document Type and Number:
WIPO Patent Application WO/2001/095366
Kind Code:
A1
Abstract:
A micro-channel plate (MCP, 1) which comprises a channel glass (3) having a plurality of channels (7) in a long and narrow form and, arranged around the glass, a peripheral glass (5), wherein the channel glass comprises, in wt %, 35 to 55 % of SiO¿2?, 0 to 5 % of Al¿2?O¿3?, 25 to 46 % of PbO, 0.5 to 10 % of $g(S)(Li¿2?O + Na¿2?O + K¿2?O), 0.1 to 8 % of $g(S)(Rb¿2?O + Cs¿2?O), 0 to 5 % of $g(S)(MgO + CaO + SrO + BaO), 0.1 to 7 % of ZrO¿2? and 0 to 5 % of Bi¿2?O¿3?. The use of a channel glass (3) having the above composition allows the formation of a satisfactory glass network and the conversion of the channel glass (3) to a porous structure being satisfactorily inhibited, which results in satisfactory suppression of the occurrence of a change with the elapse of time such as warpage even under a high temperature circumstance.
