Open publisher page 2 citations

Abstract

Photomultiplier tubes (PMTs) making use of microchannel plate (MCP) electron multiplier assemblies are being developed. Both single anode and multianode designs are available having active diameters of 18 mm, 25 mm and 40 mm. A variety of spectral sensitivities is available in all sizes, and Blue GaAs, GaAs, or InGaAs photocathodes can be provided in the 18 mm active diameter size. Pulse height distributions having full-width half-maximum values of 59% and peak-to-valley ratios of 10 have been achieved.
