WebA photocathode is a negatively charged electrode in a light detection device. They are the main type of photomultiplier. That means they take a little light, and make more of it. A photocathode is a surface engineered to convert light (photons) into electrons using the photoelectric effect. Photocathodes are important in accelerator physics where they are utilised in a photoinjector to generate high brightness electron beams. Electron beams generated with photocathodes are commonly … See more Quantum Efficiency (QE) Quantum efficiency is a unitless number that measures the sensitivity of the photocathode to light. It is the ratio of the number of electrons emitted to the number of incident … See more For many years the photocathode was the only practical method for converting light to an electron current. As such it tends to function as a form of 'electric film' and shared many characteristics of photography. It was therefore the key element in opto … See more Although a plain metallic cathode will exhibit photoelectric properties, the specialized coating greatly increases the effect. A … See more • Photomultiplier Tubes Basics and Applications from Hamamatsu Photonics See more Photocathodes operate in a vacuum, so their design parallels vacuum tube technology. Since most cathodes are sensitive to air the … See more The surface of photocathodes can be characterized by various surface sensitive techniques like scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy. See more • Ag-O-Cs, also called S-1. This was the first compound photocathode material, developed in 1929. Sensitivity from 300 nm to 1200 nm. Since Ag-O-Cs has a higher dark current than more modern materials, photomultiplier tubes with this photocathode … See more five guys in belton mo
