Paper Abstract

A photon-counting microchannel plate (MCP) photomultiplier tube (PMT) has been developed having a 28 mm active optical input diameter and ultraviolet solar-blind sensitivity. Its quantum yield is high in the uv, eg 10% at 250 nm, while the unwanted long wavelength response is greatly reduced, eg only 1.7E-6% at 600 nm. By using MCPs, this new PMT is one of the smallest to be developed to date for uv solar-blind applications. A potted assembly containing this tube and a high-voltage power supply is only 16 mm long, it has an outside diameter of 52 mm, and its mass is only 50 g. Prototype units have passed MIL-E-5400 environmental tests for class-1B equipment. Several other types of uv optical detectors are discussed which allow sub-nanosecond events to be recorded, which detect the arrival rates and locations of single photons within a 25 mm active diameter, and which have increased quantum efficiency in the far uv.
