84. High-quality electron beams and free electron lasing based on a laser wakefield accelerator at SIOM

Ke Feng (SIOM)

Invited talk

Laser wakefield accelerators (LWFAs) are capable of generating ultra-high accelerating gradient up to 100 GV/m, and hold a great potential as a candidate for driving compact free electron lasers (FELs). However, the stability and insufficient beam quality, in terms of energy spread, large initial divergence, present a substantial obstacle to the realization of high-gain FELs. With the in-house...

89. Seeded FEL lasing of the COXINEL beamline driven by the HZDR plasma accelerator

Amin Ghaith (SOLEIL)

Invited talk

Laser Plasma Accelerator (LPA) capabilities of producing high peak current, low emittance and GeV electron beams within a cm scale of accelerating distance paved the way for the realization of future compact light sources. With the continuous developments on LPA stability and electron beam properties, free electron laser (FEL) amplification had been recently demonstrated.
We report here on...

53. First SASE and Seeded FEL Lasing based on a beam driven wakefield accelerator

Mario Galletti (Istituto Nazionale di Fisica Nucleare)

21/09/2022, 18:30

Invited talk

The breakthrough provided by plasma-based accelerators enabled unprecedented accelerating fields by boosting electron beams to GeV energies within few cm.
This enables the realization of table-top accelerators able to drive a Free-Electron Laser (FEL), a formidable tool to investigate matter at sub-atomic level by generating X-UV coherent light pulses with fs and sub-fs durations.
So far,...

51. Plasma accelerator demonstration facility at intermediate energy

Carl Schroeder (Lawrence Berkeley National Laboratory)

22/09/2022, 11:20

Invited talk

It is envisioned that a future energy-frontier lepton collider would require a center-of-mass energy beyond 10 TeV. Plasma accelerators are a leading candidate technology to reach these beam energies, owing to their ability to produce gradients on the order of 10 GV/m, leading to compact accelerator structures. To realize a future plasma-based collider, intermediate facilities are required to...

39. Solutions and challenges for a multi-stage plasma accelerator

Dr Carl A. Lindstrøm (University of Oslo)

22/09/2022, 11:40

Invited talk

Particle physics requires high energies, beyond what is possible in a single plasma-accelerator stage. Coupling of stages is, however, very challenging due to chromatic aberrations and tight tolerances on synchronization. A new beam-optics scheme is proposed, based on nonlinear plasma lenses, promising to enable compact staging without degrading emittance, as well as improving tolerances on...
