Dr Carl A. Lindstrรธm (University of Oslo)22/09/2025, 16:20PS1: Plasma-based accelerators and ancillary componentsOral contribution
Plasma acceleration promises to make high-energy and high-power accelerator facilities, such as linear colliders, cheaper and more compact. However, many aspects of plasma accelerators are still at a relatively low technology readiness level (TRL). Maturing the technology requires near-term applications with moderate requirements in all but the core aspects, which in particular includes...

In recent years, plasma accelerators have advanced significantly toward producing beams suitable for colliders, aiming to replace conventional MV/m RF fields with GV/m fields of nonlinear plasma waves. Realizing a plasma-based collider requires electron bunches with high charge (hundreds of pC), low normalized emittance (~100 nm), and energy spread below 1%. Minimizing energy spread during...

Plasma wakefield acceleration (PWFA) has attracted great interest due to its large accelerating gradient, i.e. orders of magnitude higher than that in conventional accelerators. The purpose-built FEBE (Full Energy Beam Exploitation) beamline at CLARA facility at Daresbury lab will provide ultra-bright electron beams which enable us to exploit a wide range of PWFA experiments. In this talk, we...

Plasma accelerators can sustain extremely high field gradients, making them strong candidates for future X-ray sources and compact linear colliders. Achieving the high luminosity required for collider applications necessitates the use of flat beams to minimize harmful beamstrahlung effects. However, we show that flat beams in plasma accelerators are susceptible to beam quality degradation due...

Moritz Foerster (LMU Munich)22/09/2025, 18:00PS1: Plasma-based accelerators and ancillary componentsOral contribution
Hybrid laser- and electron beam-driven plasma wakefield accelerators (L-PWFAs) combine the compactness of laser wakefield acceleration (LWFA) with the beam quality and stability of particle-driven wakefield acceleration (PWFA). In this scheme, an LWFA stage generates a high-current electron bunch that drives a PWFA stage, where a witness bunch is internally injected and accelerated.

Electron beams from a wakefield accelerator are usually assumed to be short, comparable to the plasma wavelength. Under certain conditions, as the electrons start to exit the accelerator, the plasma wavelength increases and the electrons are moved into the decelerating phase of the wakefield. At this point, the electrons start to lose energy, and a fraction of them are separated and lost from...

Prof. Steven Jamison (Lancaster University)23/09/2025, 17:00PS1: Plasma-based accelerators and ancillary componentsOral contribution
The H3$^+$Beams project seeks to solve the many challenges of external injection from an RF-injector into a high-gradient LWFA structure, and to explore the physics of beam quality preservation in injection and staging.
Principal amongst the obstacles of injection from an RF-injector are the few-femtosecond synchronisation and bunch length requirements.

Laser-wakefield accelerators (LWFA) deliver high quality, mono-energetic electron beams in a compact and reliable way. Yet, achieving multi-GeV electron bunches, without requiring additional laser beams or plasma channels, remains a challenge that may require changing our approach that will facilitate the acceleration of even more energetic electron beams. For that, LWFA must overcome...

Following recent advances that have pushed LPA energy gains to the 10โฏGeV level, attention is beginning to shift toward enhancing beam quality, tunability, and reliability in this regime. In this context, we propose a novel scheme for controlling the injection of a high-quality electron bunch into a channel-guided laser-plasma accelerator. This all-optical technique, *constricted waveguide...

Michael Litos (University of Colorado Boulder)24/09/2025, 17:20PS1: Plasma-based accelerators and ancillary componentsOral contribution
To compete with conventional accelerators, collider and light source applications based on plasma wakefield acceleration need to be able to handle 10s of Joules of energy transfer between the drive beam, plasma, and witness beam at repetition rates exceeding 100 Hz. Scaling up to these parameters is challenging due to the large amount of heat deposited in the plasma source. To begin...
