Description
Abstract:
Despite the widespread success of solid state imaging devices such as CCDs, there are many fields of research and commerce where the sensitivity to detect single quanta accurately in time and space is required, a regime where signal amplification is essential. Although solid state technologies capable of photon counting are available, such as the APD and SiPM, so far these devices cannot compete in ultimate response time and signal to noise ratio compared with in vacuo electron gain devices such as the microchannel plate (MCP) image intensifier.
MCP detectors have application in many fields of science, from space-based UV and X-ray astronomy to microscopic analysis and diagnosis of living biological processes. They can be utilized for photon and particle detection in both analogue and event counting modes, and their planar geometry lends itself to imaging, where their fine pore structure provides very high spatial resolution, and their small avalanche geometry allows event timing in the picosecond regime.
I will describe the design, manufacture, and operational characteristics of MCP-based detectors, including event imaging, timing, count rate, and device lifetime performance. I will discuss some of the recent technological developments in MCP design and imaging readout techniques which extend their performance and promote possible application in fields such as fluorescence lifetime imaging for the life sciences, and Cherenkov detection for nuclear and particle physics, and astronomy.
