Improved microchannel plate performance with a resistive anode encoder
TLDR
In this paper, the performance of microchannel plates in the high-gain chevron configuration has been improved by the addition of an interplate voltage VB, and the output electron distribution FWHM decreased from 166% to 97%.Abstract:
Performance of microchannel plates in the high‐gain chevron configuration has been improved by the addition of an interplate voltage VB. For VB=100 V, and positive ion excitation, the output electron distribution FWHM decreased from 166% to 97%. Using a resistive anode encoder (RAE) readout, and 1216‐A uv excitation, we observed a corresponding spatial resolution improvement of 16%.read more

Microchannel plate detectors
TL;DR: A microchannel plate (MCP) as discussed by the authors is an array of 104-107 miniature electron multipliers oriented parallel to one another (see Fig. 1); typical channel diameters are in the range 10-100 μm and have length to diameter ratios (α) between 40 and 100.

The Gain Characteristics of Microchannel Plates for X-Ray Photon Counting
TL;DR: In this article, a theoretical and experimental study of the gain of microchannel plate (MCP) electron multipliers under conditions of output charge saturation-ation was performed, and the theoretical calculations, assuming a wall charge saturation mechanism, were used to interpret peak gain and pulse height distribution FWHM data obtained with a number of chevron MCP multipliers.

Continuous-readout extreme-ultraviolet airglow spectrometer.
TL;DR: A satellite-borne extreme-ultraviolet airglow spectrometer is described covering the 275-1420-A range with 8-A resolution, which results in a factor of 80 increase in sensitivity over a fixed exit slit design of equivalent resolution.

The Ranicon: A resistive anode image converter
Michael Lampton,F. Paresce +1 more
TL;DR: The Ranicon as mentioned in this paper is a photon and charged particle imaging system that employs a microchannel electron multiplier plate to convert each detected event into a charge signal, which is located electronically by the ratios of the charges collected at the edges or by the differences of the signals' risetimes.
