Cs-Sb Photocathode with Nesa Base

MEASURING THE SPECTRAL RESPONSE OF Cs-K-Sb PHOTOCATHODES FOR bERLinPro∗

A spectral response setup was commissioned at the Cs-K-Sb photocathode preparation and analysis system, developed for the bERLinPro project. The setup is designed to measure the spectral quantum efficiency from 370 to 700 nm, to monitor the photocurrent during the photocathode growth process and the photocathode lifetime at 515 nm.

co-precipitation of Sb(III) and Sb(V) with ferrihydrite

Elevated antimony concentrations in aqueous environments from anthropogenic sources 9 is becoming of global concern, here iron oxides are known to strongly adsorb aqueous antimony 10 species with different oxidation states, but the effect of silica on the removal characteristics is not 11 well understood despite being a common component in the environment. In this study, ferrihydrite 12 was syn...

rookhaven photocathode rf gun

The Brookhaven Accelerator Test Facility (ATF) uses a photocathode rf gun to provide a high-brightness electron beam intended for FEL and laser acceleration experiments. The rf gun consists of 1-,' cells driven at 2856 MHz in 7r-mode with a maximum cathode field of 100 MV/m. To achieve long lifetimes, our photocathode development concentrates on robust metals such as copper, yttrium and samariu...

Technology of photocathode production

Thin film photocathodes have been developed both for gas and vacuum based photodetectors. Over the last years we have gained experience in fabricating large area reflective CsI and semi-transparent monoand bialkali-cathodes, i.e. Rb2Te and K2CsSb: Today we are producing stable cathodes with excellent quantum efficiency for large MWPC based pad detectors and Hybrid Photodiodes on a routine basis...
