A retarding field photoelectron spectrometer

Variable angle photoelectron spectrometer *

The design, construction, and performance of a spectrometer for measuring the angular and energy distributions of electrons photoejected by rare gas resonance light is described. Results using 584.4-A photons from a helium lamp are reported. Flexibility of instrumental design allows for the use of other light sources. A 180° hemispherical electrostatic electron energy analyzer is rotatable abou...

A Retarding Field Energy Analyser for the JET Plasma Boundary . A Retarding Field Energy Analyser for the JET Plasma Boundary

A versatile photoelectron spectrometer for pressures up to 30 mbar.

High-pressure photoelectron spectroscopy is a rapidly developing technique with applications in a wide range of fields ranging from fundamental surface science and catalysis to energy materials, environmental science, and biology. At present the majority of the high-pressure photoelectron spectrometers are situated at synchrotron end stations, but recently a small number of laboratory-based set...

First Results from a Retarding Field Angle-Resolved Analyzer

A novel gridded retarding field energy analyzer for IEDF measurement

A retarding field energy analyzer (RFEA) has been designed and developed to measure ion energy distribution function (IEDF) in helicon plasma. To design RFEA, determination of shape, size of the analyzer orifice, choice of grid and their separations are discussed. The four grid energy analyzer assembly provides easy access of all internal mechanical components and electrical connections. Fundam...
