Parameterisation of the angular response of the R1408 Hamamatsu eight-inch photomultiplier tube to be used in the Sudbury Neutrino Observatory

1996

M. D. Lay

This paper describes measurements made on Hamamatsu R1408 8-m. photomultiplier tubes in order to parameterise the cesium bialkali photocathode in terms of a complex refractive index fi and a thickness T. The extracted parameters have been used to predict the angular response of the photomultiplier tubes, and this prediction has been experimentally verified. Measurements were taken on a number o...

High Brightness Electron Beams from a Multi- Filamentary Niobium-tin Photocathode

2013

F. Ardana-Lamas C. Vicario F. Le Pimpec A. Anghel C. P. Hauri Paul Scherrer

High-brightness electron sources are of fundamental interest for particle accelerators and modern free electron lasers. Inspired by the micro-structure of field emitter arrays [1,2] we report on a new type of metallic photo-cathode consisting of thousands of Nb3Sn micro-columns. With this metallic photocathode we could demonstrate quantum efficiencies up to 0.5% under stable operation [3,4]. Pr...

Ti3C2 MXene-based Schottky photocathode for enhanced photoelectrochemical sensing

Journal: :Journal of Alloys and Compounds 2021

Nanomaterials are vital to the realization of photoelectrochemical (PEC) sensing platform that provides sensitive detection and quantification low-abundance biological samples. Here, this work reports a Schottky junction-based BiOI/Ti3C2 heterostructure, used as photocathode for PEC bioanalysis. Specially, we realize in situ growth flower-like BiOI on 2D intrinsically negatively charged Ti3C2 M...
