专利汇可以提供Light amplifiers专利检索，专利查询，专利分析的服务。并且Microchannel plates prepared from anodized aluminum layers etched to increase the pore volume to approximately 50 percent and then treated to exhibit suitable electrical properties for use as a channel plate.，下面是Light amplifiers专利的具体信息内容。
2. The process of claim 1 wherein the impregnant is a solution of at least one alkali metal hydroxide in an alcohol selected from the group represented by the formula R-OH where R represents lower alkyl.
3. The process of claim 1 wherein the anodizable metal is aluminum and the anodizing is effected at voltages in excess of 200 volts whereby the center-to-center spacing beTween pores in the resulting anodized layer is increased to above 0.4 micron.
4. The process of claim 3 wherein the voltage is in the range of 250 to 500 volts.
5. Process of claim 1 wherein the plate is rinsed after step (e) and then subjected to heat treatment in hydrogen at about 600* C for about 1 hour to increase the electrical conductivity of the channel plate.
6. Process of claim 1 wherein the pores in the plate are doped with a reducible metal oxide during the anodizing process.
7. Process of claim 1 wherein the anodizable metal is selected from the group consisting of aluminum and aluminum-base alloys.
8. A process according to claim 7 in which the aluminum alloy is an alloy of aluminum with at least one metal such as Mg, Be, Ti, B, Mn, V, Ag and Zn so that the resulting channel plate exhibits enhanced secondary emissive properties.
9. A process according to claim 1 in which the pores in the plate are doped with salts of metals which are secondary emitters.
10. A process according to claim 9 in which the salts are salts of the alkaline and alkaline earth metals.
11. The process of claim 10 in which the salts are acetates.
