MICROCHANNEL PLATE AND METHOD OF MAKING THE MICROCHANNEL PLATE WITH METAL CONTACTS SELECTIVELY FORMED ON ONE SIDE OF CHANNEL OPENINGS

A night vision system, a microchannel plate (MCP), and a planetary deposition system and methodology are provided for selectively depositing an electrode contact metal on one side of MCP channel openings. MCPs can be secured to a face of a platter that rotates about its central platter axis. The rotating platter can be tilted on a fixture surrounding an evaporative source of contact metal. A mask with a variable size mask opening is arranged between the rotating platter and the evaporative source. While the mask orbits around the evaporative source with the rotating platter, the mask does not rotate along its own axis as does the rotating platter. Depending on the opening of the non-rotating mask, and the tilt angle of the rotating platter, the respective circumferential distance around and the depth into the shaded first side of the channel opening is controlled.

Ion detector for measuring ion output

The present invention provides methods and systems for an apparatus for the detection of ions that include a housing containing a top portion and a bottom portion, wherein the bottom portion contains a base that extends to an outer edge from which first and second pairs of spaced-apart, opposed sidewalls project upwards from the outer edge to collectively form an interior storage compartment therein. The sidewalls each have an inner and outer sidewall surfaces and each of the second pair of sidewalls interconnect the first pair of sidewalls to define corners and an interior storage compartment and an upper rim is contained on each sidewall for engaging and supporting the top portion. A circuit board is contained within the interior storage compartment, and an antenna for detecting the ions extends from the top portion.
