Development of high-speed microchannel photomultiplier

D. Simmons, Brigette Smith, Brent Davis, P. B. Lyons

Abstract

Progress in the development of a high-speed microchannel plate (MCP) photomultiplier is reviewed. The device consists of a semitransparent photocathode and MCP with a tapered 50 ohm anode. Two prototypes have been built and evaluated. One has an accelerating screen between the MCP and anode. The other has no screen, but is otherwise identical. Time response data is presented for the two prototypes showing the effect of the screen.
