Reflective UV photocathodes with gas-phase electron extraction: solid, liquid, and adsorbed thin films
TL;DR: In this article, the photoemission quantum efficiency of reflective photocathodes in methane gas has been investigated in the spectral range between 140 and 250 nm, and the spectral response of solid metals and CsI, as well as of liquid and solid TMAE film, have been measured.

Theory of ring imaging Cherenkov counters
T. Ypsilantis,J. Seguinot +1 more
TL;DR: A short review of Cherenkov radiation and its use for particle identification with threshold and differential counters is presented in this article, where the focusing principles of Ring Imaging Cherankov (RICH) counters are then developed and applied successively to gas and liquid radiators.

Gaseous Radiation Detectors: Fundamentals and Applications
TL;DR: In this article, the authors describe the drift and diffusion of charges in gases, collisional excitations and charge multiplication in uniform fields, and drift chambers and time projection chambers for time degeneracy and aging.

A historical survey of ring imaging Cherenkov counters
J. Seguinot,T. Ypsilantis +1 more
TL;DR: Ring Imaging Cherenkov (RICH) counters as discussed by the authors have been used for particle identification since 1977, and have been classified into three groups, each developed over the last sixteen years, but based on different techniques and readout methods.

Coded aperture imaging - Predicted performance of uniformly redundant arrays
TL;DR: A general expression for the signal-to-noise ratio (SNR) has been developed for the URA as a function of the type of object being imaged and the design parameters of the aperture.
Journal ArticleDOI
Ionization fluctuations and resolution of ionization chambers and semiconductor detectors
TL;DR: In this paper, the Fano factor for a variety of gases and for Si and Ge was calculated by Fano's approximate method, and the authors concluded that the ultimate fwhm of gas ionization chambers may be 7 keV at an α-particle energy of 6 MeV.

Progress in high-accuracy proportional chambers
TL;DR: In this paper, the position of the ion cloud, using pulses induced in cathode strips arising from absorption of low-energy X-rays, is defined for ionizing events punctually localized in the volume of a proportional chamber, and the mean position of corresponding avalanches are well defined.

Tomographical imaging using uniformly redundant arrays.
T. M. Cannon,E. E. Fenimore +1 more
TL;DR: This paper investigates the performance of two URA apertures when used in a close-up tomographic imaging system and shows that a URA based on m sequences is superior to one based on quadratic residues.

A large area, gas scintillation proportional counter
TL;DR: In this paper, an improved gas scintillation proportional counter with a measured overall energy resolution of 9.3% at 5.9 keV has been built, which is sufficiently well defined to allow the use of pulse-shape discrimination to reject 86% of the non-X-ray events in a space environment.
