WG8 - Advanced and novel accelerators for High Energy Physics
talk
In this talk we will discuss the present concepts of plasma-based colliders, and in particular will discuss the sub-systems of the design, reviewing the assumptions and exploring if conventional sub-systems can be replaced, in some cases, by advanced designs.

Energy spread caused by the longitudinal size of the beam is well known in PWFA. Usually this issue can be resolved with beam loading effect that allows to keep accelerating field constant, or close to constant, along all the duration of the beam. In this work however, we would like to address another source of energy spread, that arises at higher energies - betatron radiation.

Plasma lenses in the underdense regime have been shown to give extremely strong linear focusing, with strength proportional to the local plasma ion density. This technique has been proposed as the basis of an scheme for future linear colliders that mitigates the Oide effect through adiabatic focusing. In this scenario the plasma density in the lens is ramped slowly on the scale of betatron...

Proton-driven plasma wakefield acceleration has recently been proposed to accelerate a bunch of electrons to more than 600 GeV in a single stage of acceleration. This may pave the way to realising the energy frontier colliders based on this scheme in the future. However, the resulting beam quality and luminosity are not good enough for the direct applications. In this paper, we propose a new...

Dielectric Laser-driven Acceleration (DLA) refers to the acceleration of particles inside a vacuum channel within a dielectric structure powered by near infrared lasers. Recent demontrations of accelerating gradients approaching 1 GeV/m, improvements in energy gain, numerically optimized structure designs, and development of a variety of auxilliary laser-driven concepts for focusing,...

The development of advanced acceleration methods with a large acceleration gradient, much larger than achieved in conventional radio frequency accelerators, is necessary to reach a TeV-energy range for future electron-positron colliders. One of the possible approaches is based on the multistage acceleration in the wakefields generated in plasma by relativistic-intense femtosecond laser...

talk
A perspective scheme of accelerators suitable for high energy physics experiments is a multi stage laser wakefield acceleration. Relativistic electron bunch accelerated in the laser wakefields undergoes betatron oscillations and emits synchrotron radiation that affects the dynamics of electron motion and polarization. A model for numerical simulation of the acceleration of polarized electrons...

Turning the current experimental plasma accelerator state-of-the-art from a promising technology into mainstream scientific tools depends critically on high-performance, high-fidelity modeling of complex processes that develop over a wide range of space and time scales. As part of the U.S. Department of Energy’s Exascale Computing Project, a team from Lawrence Berkeley National Laboratory, in...
