1. Photomultipliers: Their Cause and Cure†
TL;DR: In this paper, the basic physics and construction of photomultipliers are described, and it is suggested that the area of the photocathode illuminated during measurements, and the wavelength of the radiation, are the same as those used during calibration.
Optical enhancement of photomultiplier sensitivity
G. R. Grant,W. D. Gunter +1 more
TL;DR: In this paper, the authors introduced light into end-window of device at an angle large enough to normal so total internal reflection occurs at both photocathode-vacuum and window-air interfaces.

Photoemission of Electrons from Silicon into Silicon Dioxide
TL;DR: In this article, it was shown that the current is due to photoemission of electrons from the silicon into the Si${\mathrm{O}}_{2}$ conduction band.
Journal ArticleDOI
Enhancement of photomultiplier sensitivity by total internal reflection.
TL;DR: In this article, a very thin semitransparent photocathode and total internal reflection was used to enhance the sensitivity of a photomultiplier tube with very thin semi-transparent polysilicon material.

High absolute photocathode sensitivity.

Analysis of a multiple reflective translucent photocathode.
John R. Sizelove,John A. Love +1 more
TL;DR: A mathematical absorption-diffusion model is used to study the effects of skewed incidence of light on the quantum efficiency of state-of-the-art photocathodes, and a gain of 3.5 is predicted for the smallest absorption coefficient-photocathode thickness product.

Escape probability of photoelectrons into vacuum.
John A. Love,John R. Sizelove +1 more
TL;DR: This comparison (ratio) shows that the irdegradation is due primarily to the poor escape probability of a low energy photoelectron over the surface potential barrier rather than degradation in absorption.
