Pepper-pot emittance measurement of laser-plasma wakefield accelerated electrons [PDF]
, 2009 The transverse emittance is an important parameter governing the brightness of an electron beam. Here we present the first pepper-pot measurement of the transverse emittance for a mono-energetic electron beam from a laser-plasma wakefield accelerator ...

High-resolution maps of the characteristic energy of precipitating auroral particles [PDF]
, 2001 For the first time we produce high-resolution maps of the characteristic energy of precipitating electrons from ground-based instrumentation in the auroral zone over northern Scandinavia. This is done by combining intensity-calibrated optical data at 557.

The effects of field emitted electrons on RF surfaces [PDF]
, 2009 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 ...

Dynamics of Site Selectivity in Dissociative Electron Attachment in Aromatic Molecules
Atoms, 2022 Dissociative electron attachment has shown site selectivity in aliphatic molecules based on the functional groups present in them. This selectivity arises from the core excited resonances that have excited parent states localized to a specific site of ...
