Laser-plasma accelerators are a promising technology for compact drivers of linear colliders and secondary radiation sources. To maximize single-stage energy gain, the high-intensity drive laser pulse must be kept focused over several tens of centimeters through a sufficiently low-density plasma. Recently, we employed plasma channels based on the hydrodynamic expansion of optical field ionized...

Laser-plasma acceleration has enormous potential to provide compact sources of ultra-short ion beams. Several factors, such as the low shot-to-shot stability, large beam divergence and the difficulty of high-repetition rate operation, hamper their wider adoption. Recent work demonstrates an approach for overcoming these challenges using a novel liquid sheet target, developed at the SLAC...

Plasma-wakefield acceleration holds great promise for particle physics due to its orders-of-magnitude higher accelerating gradients, which can result in significant cost reductions based on a sizeable reduction in footprint. However, plasma-based acceleration of positronsโrequired for an electron-positron colliderโis much more difficult than for electrons. In 2023 a novel collider scheme,...

Particle-driven wakefield acceleration (PWFA) promises the generation of high-brightness relativistic beams, as it allows dephasing-free acceleration and the implementation of various cold injection schemes, unlike laser-driven wakefield acceleration (LWFA). To keep the whole accelerator compact, generating the PWFA driver beam via LWFA is a promising concept [1] and the first proof of...

Laser-plasma accelerators produce electron beams whose properties depend on a complex, nonlinear relationship between numerous laser and plasma parameters. Neural networks offer a powerful tool for modelling this relationship using experimental datasets.

Beam driven wakefield acceleration in dielectric lined waveguide structures, or similarly corrugated metallic waveguides, produces high acceleration fields but also produces coupling to transverse modes. Transverse modes can lead to beam breakup and degradation of the drive beam. Employing flat beams with highly asymmetric emittance in dielectric structures with planar geometry, has been...
