A high-flux electron detection system to measure non-linear Compton scattering at LUXE
Antonios Athanassiadis, Oleksandr Borysov, Florian Burkart +16
This paper presents the development and testing of a high-flux electron detection system designed to measure the energy spectrum of more than electrons from laser-electron c…
Optical superradiance from single-digit-femtosecond electron beam structure
Chad Pennington, Gia Azcoitia, Blae Stacey +5
We report measurements of superradiant optical transition radiation in the 550-800 nm range produced by ultrashort relativistic electron bunches at a dielectric boundary. In the me…
Experimental demonstration of a tomographic 5D phase-space reconstruction
S. Jaster-Merz, R. W. Assmann, J. Beinortaitė +17
Detailed knowledge of particle-beam properties is of great importance to understand and push the performance of existing and next-generation particle accelerators. We recently prop…
electronCT -- An Imaging Technique Using Very-high Energy Electrons
Paul Schütze, Aenne Abel, Florian Burkart +12
The electronCT technique is an imaging method based on the multiple Coulomb scattering of relativistic electrons and has potential applications in medical and industrial imaging. I…
Characterization of relativistic electron bunch duration and travelling wave structure phase velocity based on momentum spectra measurements on the ARES linac at DESY
T. Vinatier, R. W. Assmann, C. Bruni +7
The ARES linac at DESY aims to generate and characterize ultrashort electron bunches (fs to sub-fs duration) with high momentum and arrival time stability for the purpose of applic…
Learning to Do or Learning While Doing: Reinforcement Learning and Bayesian Optimisation for Online Continuous Tuning
Jan Kaiser, Chenran Xu, Annika Eichler +9
Online tuning of real-world plants is a complex optimisation problem that continues to require manual intervention by experienced human operators. Autonomous tuning is a rapidly ex…
Predicting the transverse emittance of space charge dominated beams using the phase advance scan technique and a fully connected neural network
F. Mayet, M. Hachmann, K. Floettmann +5
The transverse emittance of a charged particle beam is an important figure of merit for many accelerator applications, such as ultra-fast electron diffraction, free electron lasers…
Commissioning results and electron beam characterization at the S-band photoinjector at SINBAD-ARES
E. Panofski, R. W. Assmann, F. Burkart +12
Over the last years, the generation and acceleration of ultra-short, high quality electron beams has attracted more and more interest in accelerator science. Electron bunches with…
