Synchrotrons often employ octupole magnets to Landau dampen coherent transverse instabilities, at the expense of restricting the dynamic aperture due to the excitation of betatron resonances. A very good example is the CERN Large Hadron Collider, where the octupole current required for beam stabilisation strongly impacted beam lifetime during Run 2. At the high-intensity frontier, the...
CLARA is an ultrabright electron beam test facility at STFC Daresbury Laboratory, aiming to provide high-quality, ultra-short electron bunches with charges up to 250 pC. CLARA is currently undergoing technical systems commissioning, in preparation for final beam commissioning in the summer of 2025. As part of the commissioning process, CLARA has achieved many of its major milestones,...
Physics routinely conspires to enlarge a beam's emittance. Storage ring designers and modellers, in order to provide realistic predictions, must remain aware of different sources (causes) of emittance. In this talk, I try to make the case for why diffusion processes, an often underappreciated lens with which to see electron dynamics, is likely the cause of emittance growth within your system....
CLARA is an ultrabright electron beam test facility at STFC Daresbury Laboratory, providing high-quality electron bunches with charges up to 250 pC. CLARA has recently resumed operations after a major upgrade, and is currently undergoing beam commissioning at its nominal momentum (250 MeV/c) and repetition rate (100 Hz). Accurate measurements of the transverse beam optics will be essential for...
We present a theoretical description of the radiative and space-charge intra-bunch interaction of a compact charged bunch undergoing high-field acceleration relevant to LWFA, PWFA conditions. The effects during the process of acceleration are considered specifically, in contrast to previous work that assumes an instantaneous change in energy and examines the post-acceleration interaction with...
UK XFEL is a multi-stage project to pursue 'next-generation’ XFEL capabilities, either through developing a new facility in the UK or by investing at existing machines. The project’s Science Case envisages a step-change increase in the number of simultaneous experiments, with transform-limited (‘laser-like’) x-rays across a wide range of pulse durations and photon energies (up to ~20 keV)...
Proton accelerators are central to a wide range of applications, particularly in healthcare—for radioisotope production in nuclear medicine and precision cancer therapy. The Laser-Driven Travelling-Wave Accelerator (L-TWA) introduces a compact, high-gradient alternative to conventional RF-based systems. This approach leverages intense laser-plasma interactions to generate picosecond...
X-ray free-electron laser (FEL) facilities rely on high-brightness electron bunches to deliver coherent, laser-like pulses on the femtosecond time scale at short wavelengths. Developments in electron sources and injector technology are pushing the limits on the beam emittance and energy spread, aiming to increase the bunch density in 6D phase space in order to optimise the properties of the...
In the coming decades, numerous designs for new accelerator-based facilities, or potential upgrades to current facilities, have been proposed to support the next generation of scientific advancement. While these facilities have significant scientific, economic, and societal benefits, they also require considerable resources to operate effectively. Amid the ongoing climate crisis, these...
Laser-plasma ion acceleration is a well established field of research, with several mechanisms being exploited to produce high energy, short particle beams.
Scaling laws show that both the laser's vector potential, and the critical density scale favorably with laser wavelength. Hence the long wavelength (9.2μm) CO₂ laser at the Brookhaven National Laboratories is the ideal choice for...
The European Committee for Future Accelerators (ECFA) advises CERN and its member states on long-term planning for European high-energy facilities, fostering coordination across laboratories, universities, and international organisations.
Since late 2024, ECFA-UK has consulted the particle physics community—including related areas such as accelerators, computing, and detector development—to...
The UK XFEL project envisions a transformative approach to the next-generation X-ray free-electron laser (XFEL) development by integrating emerging accelerator concepts [1] within its Conceptual Design and Options Analysis (CDOA) framework. As part of a future upgrade pathway, the project aims to ensure long-term scientific impact by exploring compact, efficient, high-performance solutions for...
There is a growing demand for generating and transporting short femtosecond-scale, high-charge-density relativistic electron bunches. Applications range from extreme light sources such as free-electron lasers (FELs) to future linear colliders and plasma accelerators. Laser-plasma wakefield accelerators (LWFA) offer a promising approach for compact high-gradient acceleration. However, electrons...
