Surrogate Models studies for laser-plasma accelerator electron source design through numerical optimisation
G. Kane, P. Drobniak, S. Kazamias +8
Designing a high-quality plasma injector electron source driven by a laser beam relies on numerical parametric studies using particle-in-cell codes. The common input parameters to…
Integration of Machine Learning-Based Plasma Acceleration Simulations into Geant4: A Case Study with the PALLAS Experiment
A. Sytov, K. Cassou, V. Kubytskyi +2
We present the development and integration of a Machine Learning (ML)-based surrogate model, trained on Particle-In-Cell (PIC) simulations of laser-driven plasma wakefield accelera…
Modelling of laser-plasma acceleration of relativistic electrons in the frame of ESCULAP project
E. Baynard, C. Bruni, K. Cassou +19
We present numerical simulations results on the injection and acceleration of a 10 MeV, 10 pC electrons beam in a plasma wave generated in a gas cell by a 2J, 45 fs laser beam. Thi…
Longitudinal compression and transverse matching of electron bunch for external injection LPWA at ESCULAP
K. Wang, E. Baynard, C. Bruni +19
We present theoretical and numerical studies of longitudinal compression and transverse matching of electron bunch before injecting into the Laser-plasma Wake Field Accelerator (LW…
Positron sources: from conventional to advanced accelerator concepts-based colliders
I. Chaikovska, R. Chehab, V. Kubytskyi +9
Positron sources are the key elements for the future and current lepton collider projects such as ILC, CLIC, SuperKEKB, FCC-ee, Muon Collider/LEMMA, etc., introducing challenging c…
Injection Feedback for a Storage Ring
A. Moutardier, N. Delerue, C. Bruni +5
We report on an injection feedback scheme for the ThomX storage ring project. ThomX is a 50-MeV-electron accelerator prototype which will use Compton backscattering in a storage ri…
Evaluation of Beam Halo from Beam-Gas Scattering at the KEK-ATF
R. Yang, T. Naito, S. Bai +9
In circular colliders, as well as in damping rings and synchrotron radiation light sources, beam halo is one of the critical issues limiting the performance as well as potentially…
LEETECH facility as a flexible source of low energy electrons
D. Attie, S. Barsuk, O. Bezshyyko +14
A new versatile facility LEETECH for detector R&D, tests and calibration is designed and constructed. It uses electrons produced by the photoinjector PHIL at LAL, Orsay and provide…
Loss maps along the ThomX transfer line and the ring first turn
A. Moutardier, C. Bruni, I. Chaikovska +5
We report on studies of the loss maps for particles travelling from the end of the ThomX's linac along the transfer line to the end of the ring first turn in preparation of the mac…
