BTF measurements with beam-beam interactions

, 2014
We present considerations about the transverse beam transfer function (BTF) of beams under the influence of two effects: The strong-strong beam-beam effect and the influence of a Gaussian electron lens.

Stochasticity effects in quantum radiation reaction [PDF]

, 2013
When an ultrarelativistic electron beam collides with a sufficiently intense laser pulse, radiation-reaction effects can strongly alter the beam dynamics.

Collimation with Hollow Electron Beams

Physical Review Letters, 2011
A novel concept of controlled halo removal for intense high-energy beams in storage rings and colliders is presented. It is based on the interaction of the circulating beam with a 5-keV, magnetically confined, pulsed hollow electron beam in a 2-m-long section of the ring.

Electron-beam spectroscopy for nanophotonics [PDF]

Nature Materials, 2019
Progress in electron-beam spectroscopies has recently enabled the study of optical excitations with combined space, energy and time resolution in the nanometer, millielectronvolt and femtosecond domain, thus providing unique access into nanophotonic structures and their detailed optical responses.

Composition formulas of Fe-based transition metals-metalloid bulk metallic glasses derived from dual-cluster model of binary eutectics

Scientific Reports, 2017
It is known that bulk metallic glasses follow simple composition formulas [cluster](glue atom)1 or 3 with 24 valence electrons within the framework of the cluster-plus-glue-atom model.

Effect of laser surface cleaning of corroded 304L stainless steel on microstructure and mechanical properties

Journal of Materials Research and Technology, 2022
In this study, a high-power Nd:YAG laser is used to remove a corrosion layer on the surface of 304L stainless steel (SS304L). A laser power of 1140 W with different hatch distances and the number of repetitions is employed for corrosion removal. As shown

The Side-Effects of the Space Charge Field Introduced by Hollow Electron Beam in the Electron Cooler of CSRm

, 2015
Electron cooler is used to improve the quality of the beam in synchrotron, however it also introduces nonlinear electromagnetic field, which cause tuneshift, tunespread and may drive resonances leading to beam loss.

Dosimetry for low-energy electron beam applications at Fraunhofer FEP

Nukleonika
Accelerating electrons to achieve chemical and biological effects is a well-established competence of Fraunhofer FEP. Today, there is a large variety of low-energy electron beam applications with a broad range of absorbed doses, e.g.
