Beam Induced Multipacting [PDF]

, 1997
Beam induced multipacting driven by the electric field of successive bunches, as first observed in the ISR proton-proton storage ring [1] may arise from a resonance motion of a cloud of secondary electrons bouncing back and forth between opposite walls ...

Cryogenic surface resistance of copper: Investigation of the impact of surface treatments for secondary electron yield reduction

Physical Review Accelerators and Beams, 2019
The surface resistance of copper samples with an amorphous carbon (a-C) coating or with laser surface structuring, the surface treatments of choice for electron cloud suppression in critical cryogenic sectors of the high-luminosity upgrade of the Large ...

Secondary amine-initiated three-component synthesis of 3,4-dihydropyrimidinones and thiones involving alkynes, aldehydes and thiourea/urea

Beilstein Journal of Organic Chemistry, 2014
The three-component reactions of aldehydes, electron deficient alkynes and ureas/thioureas have been smoothly performed to yield a class of unprecedented 3,4-dihydropyrimidinones and thiones (DHPMs).

Secondary electron emission characteristics of Al2O3 coatings prepared by atomic layer deposition

AIP Advances, 2019
Secondary electron emission (SEE) plays a crucial role in the gain performance of devices, such as electron multipliers and microchannel plates (MCPs). Gain performance could be improved by increasing the secondary electron yield (SEY) of device surface.

Electron Stimulated Desorption of Condensed Gases on Cryogenic Surfaces [PDF]

, 2005
In ultra-high vacuum systems outgassing from vacuum chamber walls and desorption from surface adsorbates are usually the factors which in°uence pressure and residual gas composition.

Surface discharge through an insulator in a vacuum [PDF]

A model for the mechanism of stationary discharges over insulators in a vacuum was developed. Upon introduction of this discharge, the insulator charges as a result of secondary emissions, in such a way that electrons coming from the cathode strike with ...

On the possibility of positive-ion detection in gaseous TPCs and its potential use for neutrinoless double beta decay searches in Xe-136

, 2017
The neutralization of slow positive ions on solid surfaces can lead to the emission of secondary electrons in Auger-type processes. We discuss the possibility of harnessing such mechanisms to the detection of positive ions in gaseous TPCs.

Ion sputter textured graphite electrode plates [PDF]

, 1983
A specially textured surface of pyrolytic graphite exhibits extremely low yields of secondary electrons and reduced numbers of reflected primary electrons after impingement of high energy primary electrons.
