Electron-stimulated desorption of potassium and cesium atoms from oxidized molybdenum surfaces

The electron-stimulated desorption (ESD) yields and energy distributions for potassium (K) and cesium (Cs) atoms have been measured from K and Cs layers adsorbed at 300 K on oxidized molybdenum surfaces with various degrees of oxidation. The measurements were carried out using a time-of-flight method and surface ionization detector. The ESD appearance threshold for K and Cs atoms is independent...

Nitrate removal from water using alum and ferric chloride: A comparative study of alum and ferric chloride efficiency

Background: Nitrate is an acute and well-known hazardous contaminant, and its contamination of water sources has been a growing concern worldwide in recent years. This study evaluated the feasibility of nitrate removal from water using the traditional coagulants alum and ferric chloride with lower concentrations than those used in the conventional coagulation process. Methods: In this research...

Multiphoton Emission from Cesium Telluride Photocathodes

The High-Brightness Electron Source Lab (HBESL) at Fermilab operates an L-band RF gun (1.3-GHz) that incorporates a Cesium Telluride (Cs2Te) photocathode illuminated by an ultra-short (sub-100 fs) laser pulses. In this contribution we report recent studies on exploring the electron beam emission using 800 nm laser pulses (instead of the 266 nm nominal wavelength used for linear photoemission). ...

Cesium from Pollucite by Aluminum Reduction

Aluminum metal was found to liberate cesium almost quantitatively from pollucite ore when reacted under conditions of operation determined by experiments described in the paper. In the treatment, ore ground to pass a 150 mesh sieve is mixed with atomized aluminum and the mixture heated under an inert atmosphere in a retort. Pollucite ore from one source yielded its cesium when treated at 950°C ...
