Abstract

Digital signal processing techniques were employed to investigate the joint use of charge division and risetime analyses for the resistive anode (RA) coupled to a microchannel plate detector (MCP). In contrast to the typical approach of using the relative charge at each corner of the RA, this joint approach results in a significantly improved position resolution. A conventional charge division analysis utilizing analog signal processing provides a measured position resolution of 170 μm (FWHM). By using the correlation between risetime and position we were able to obtain a measured resolution of 92μm (FWHM), corresponding to an intrinsic resolution of 64μm (FWHM) for a single Z-stack MCP detector.

Optimizing the position resolution of a Z-stack microchannel plate resistive anode detector for low intensity signals

Journal Article Wiggins, B. B. ; Richardson, E. ; Siwal, D. ; ... - Review of Scientific Instruments

A method for achieving good position resolution of low-intensity electron signals using a microchannel plate resistive anode detector is demonstrated. Electron events at a rate of 7 counts s{sup −1} are detected using a Z-stack microchannel plate. The dependence of position resolution on both the distance and the potential difference between the microchannel plate and resistive anode is investigated. Using standard commercial electronics, a measured position resolution of 170 μm (FWHM) is obtained, which corresponds to an intrinsic resolution of 157 μm (FWHM)

Achieving high spatial resolution using a microchannel plate detector with an economic and scalable approach

Journal Article Wiggins, B. B. ; deSouza, Z. O. ; Vadas, J. ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

We report a second generation position-sensitive microchannel plate detector using the induced signal approach has been realized. This detector is presently capable of measuring the incident position of electrons, photons, or ions. To assess the spatial resolution, the masked detector was illuminated by electrons. The initial, measured spatial resolution of 276 μm FWHM was improved by requiring a minimum signal amplitude on the anode and by employing digital signal processing techniques. The resulting measured spatial resolution of 119 μm FWHM corresponds to an intrinsic resolution of 98 μm FWHM when the effect of the finite slit width is de-convoluted. Thismore »« less

Development of a compact $E ? B$ microchannel plate detector for beam imaging

Journal Article Wiggins, B. B. ; Singh, Varinderjit ; Vadas, J. ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

A beam imaging detector was developed by coupling a multi-strip anode with delay line readout to an E×B microchannel plate (MCP) detector. This detector is capable of measuring the incident position of the beam particles in one-dimension. To assess the spatial resolution, the detector was illuminated by an α-source with an intervening mask that consists of a series of precisely-machined slits. The measured spatial resolution was 520 um source FWHM, which was improved to 413 um FWHM by performing an FFT of the signals, rejecting spurious signals on the delay line, and requiring a minimum signal amplitude. This measured spatialmore »« less

An efficient and cost-effective microchannel plate detector for slow neutron radiography

Journal Article Wiggins, B. B. ; Vadas, J. ; Bancroft, D. ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

We report a novel approach for efficiently imaging objects with slow neutrons in two dimensions is realized. Neutron sensitivity is achieved by use of a boron doped microchannel plate (MCP). The resulting electron avalanche is further amplified with a Z-stack MCP before being sensed by two orthogonally oriented wire planes. Coupling of the wire planes to delay lines efficiently encodes the position information as a time difference. To determine the position resolution, slow neutrons were used to illuminate a Cd-mask placed directly in front of the detector. Peaks in the resulting spectrum exhibited an average peak width of 329 μmmore »« less

Microchannel plate pore size limited imaging with ultra-thin wedge and strip anodes

Conference Lapington, J S ; Smith, A D ; Walton, D M ; ... - IEEE Trans. Nucl. Sci.; (United States)

The authors describe a detector employing a curved channel microchannel plate (MCP) in front of an optimised, thin substrate wedge and strip anode (WSA) imaging readout. They obtain a position resolution better than 20..mu..m FWHM allowing the images of individual MCP pores to be distinguished. The collimation provided by a single pore is used to probe the fundamental limitations in resolution of the WSA. Finally, having experimentally verified the limitations imposed by electronic and partition noise, the authors describe a detector which will produce 20..mu..m FWHM resolution over a 50mm diameter imaging area.
