Paper Abstract

Magnetic field focusing of electrons affords higher spatial resolution as compared to the proximity focusing employed in most microchannel plate image intensifier tubes currently being manufactured.1,2,3 Magnetic focusing also affords a means of rotating the optical image between the photocathode and anode. A special 40 mm diameter MCP tube fabricated by ITT with 98 mm spacing between the photocathode and MCP has been evaluated to compare its spatial frequency response with that of a conventional proximity focused MCP image tube and to study effecting controlled electronic image rotation as a function of the ratio of magnetic field strength at the photocathode and MCP.
