The Effects of Field Emitted Electrons on Rf Surface

The ever-growing demand for higher RF gradients has considerably increased the risk of breakdown in accelerating structures. Field emission is the most common form of RF breakdown that generates free electrons capable of inflicting irreversible damages on the RF surface. This paper presents a systematic experimental and simulation programme to understand possible sources and their influence on ...

Energy Spectra of Auto-Ionizing Electrons in Oxygen

Energy spectra of two electrons in a circular quantum dot

The energy spectrum of two interacting electrons in a flat circular quantum dot is investigated. While the centre of motion can be treated exactly, the Wentzel-Kramers-Brillouin (WKB) approximation has been applied to study the relative motion. The energies are seen to agree well with the exact numerical results.

3D Simulation of the Effects of Surface Defects on Field Emitted Electrons

The ever-growing demand for higher RF gradients has considerably increased the risk of breakdown in accelerating structures. Field emission is the most common form of RF breakdown that generates free electrons capable of inflicting irreversible damages on the RF surface. This paper presents a simulation study to understand the effects of defects on local fields and behaviour of field emitted el...
