Slice Emittance Preservation and Focus Control in a Passive Plasma Lens
J. Björklund Svensson, J. Beinortaitė, L. Boulton +15
Strong, symmetrically focusing plasma lenses are promising for accommodating the small beams associated with plasma-based accelerators and collider final foci. However, while focus…
Characterization of discharge capillaries via benchmarked hydrodynamic plasma simulations
S. M. Mewes, G. J. Boyle, R. D'Arcy +10
Plasma accelerators utilize strong electric fields in plasma waves to accelerate charged particles, making them a compact alternative to radiofrequency technologies. Discharge capi…
Ion-motion simulations of a plasma-wakefield experiment at FLASHForward
D. Kalvik, P. Drobniak, F. Peña +13
In plasma-based acceleration, an ultra-relativistic particle bunch$\unicode{x2014}$or an intense laser beam$\unicode{x2014}$is used to expel electrons from its propagation path, fo…
Updated baseline design for HALHF: the hybrid, asymmetric, linear Higgs factory
C. A. Lindstrøm, E. Adli, J. B. B. Chen +25
Particle physicists aim to construct a electron-positron Higgs factory as the next major particle collider. However, the high associated costs motivate the development of more affo…
Preliminary results from the CLEAR nonlinear plasma lens experiment
P. Drobniak, E. Adli, H. B. Anderson +5
Plasma lensing provides compact focusing of electron beams, since they offer strong focusing fields (kT/m) in both planes simultaneously. This becomes particularly important for hi…
HALHF: a hybrid, asymmetric, linear Higgs factory using plasma- and RF-based acceleration. Backup Document
Erik Adli, Joshua Appleby, Timothy L. Barklow +59
This document expands on the Comprehensive Summary submitted to the EPPSU 2026. It contains details on aspects of the HALHF project that could not be fitted into the Summary. Some…
HALHF: a hybrid, asymmetric, linear Higgs factory using plasma- and RF-based acceleration
Erik Adli, Joshua Appleby, Timothy L. Barklow +59
HALHF is a hybrid linear collider that uses electron-driven plasma-wakefield acceleration to accelerate electrons to high energy while using radio-frequency cavity technology to ac…
Development of a nonlinear plasma lens for achromatic beam transport
P. Drobniak, E. Adli, H. Bergravf Anderson +5
We introduce the new idea of a nonlinear active plasma lens, as part of a larger transport lattice for achromatic electron beam transport. The proposed implementation is based on u…
