Abstract
The present invention relates to a low-resistance MCP with an expanded dynamic range and excellent environment resistance, in comparison with the conventional technology. The MCP has a double structure composed of hollow first cladding glasses whose inner wall surfaces function as channel walls, and a second cladding glass having an acid resistance higher than that of the first cladding glasses.
Claims19
A microchannel plate comprising a main body comprised of lead glass which exhibits electric insulation before a reduction treatment and exhibits electric conduction after the reduction treatment,
- wherein the main body comprises:
- first cladding glasses each of which has a hollow structure extending along a predetermined direction;
- and
- a second cladding glass which is located at least in part in spaces among outer peripheral surfaces of the first cladding glasses in a state in which the second cladding glass is in contact with the outer peripheral surfaces of the respective first cladding glasses, and
- wherein in comparison before the reduction treatment, the first cladding glasses have an acid resistance higher than an acid resistance of the second cladding glass.
A microchannel plate comprising a main body comprised of lead glass which exhibits electric insulation before a reduction treatment and exhibits electric conduction after the reduction treatment,
- wherein the main body comprises:
- a cladding glass which has through holes each extending along a predetermined direction and which contains lead oxide at a weight percentage of not less than 48.0% and less than 65% before the reduction treatment;
- and
- a coating material which is provided on inner walls of the through holes in the cladding glass and which has an acid resistance before the reduction treatment higher than an acid resistance of the cladding glass before the reduction treatment.
