A new approach to solving the radiation field problem of an extended helical undulator
M. I. Ivanyan, B. Grigoryan, A. Grigoryan +6
A new method is applied to construct an exact solution for the radiation field of a particle moving along an infinite helical trajectory. The solution is obtained in the form of a…
Optimization of the Resolution of a Streaking Setup
F. Mayet, K. Floettmann
In low regimes the inevitable induced energy spread in combination with longitudinal dispersion during the drift through a transverse deflecting structure (TDS) can alter the…
Start-to-End Simulations of SASE FEL at the TESLA Test Facility, Phase 1
M. Dohlus, K. Floettmann, O. S. Kozlov +5
Phase 1 of the vacuum ultra-violet (VUV) free-electron laser (FEL) at the TESLA Test Facility (TTF) recently concluded operation. It successfully demonstrated the saturation of a S…
Chirp mitigation of plasma-accelerated beams using a modulated plasma density
R. Brinkmann, N. Delbos, I. Dornmair +13
Plasma-based accelerators offer the possibility to drive future compact light sources and high-energy physics applications. Achieving good beam quality, especially a small beam ene…
Direct Measurement of Focusing Fields in Active Plasma Lenses
J. -H. Röckemann, L. Schaper, S. K. Barber +17
Active plasma lenses have the potential to enable broad-ranging applications of plasma-based accelerators owing to their compact design and radially symmetric kT/m-level focusing f…
Plasma-driven ultrashort bunch diagnostic
I. Dornmair, C. B. Schroeder, K. Floettmann +2
Ultrashort electron bunches are crucial for an increasing number of applications, however, diagnosing their longitudinal phase space remains a challenge. We propose a new method th…
The Flat Beam Experiment at the FNAL Photoinjector
D. Edwards, H. Edwards, N. Holtkamp +7
A technique for production of an electron beam with a high transverse emittance ratio. a "flat" beam, has been proposed by Brinkmann, Derbenev, and Floettmann.[1] The cathode of an…
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…
