Achromatic optics using nonlinear plasma lenses for beam-quality preservation between plasma-accelerator stages
C. A. Lindstrøm, E. Adli, J. B. B. Chen +6
Plasma acceleration promises to deliver high-energy particle beams by combining, or staging, several low- or medium-energy accelerator stages. However, chromatic aberrations from t…
Strong-field focusing of high-energy particles in beam-multifoil collisions
Aimé Matheron, Doug Storey, Max F. Gilljohann +25
Extreme beams of charged particles and photons, reaching ultrahigh densities or producing intense gamma-ray bursts, are central to accelerator physics, laboratory astrophysics, and…
First results from the E302 efficiency$\unicode{x2013}$instability experiment at the FACET-II facility
O. G. Finnerud, E. Adli, R. Ariniello +18
The beam-breakup (BBU) instability in plasma accelerators is seeded by a transverse offset between the driver and a trailing bunch. The BBU instability induces oscillations in the…
Driver-delay chicanes for a multistage plasma-based accelerator facility
D. Kalvik, E. Adli, P. Drobniak +2
The SPARTA project aims to design a medium-sized accelerator facility that facilitates new experiments in strong-field quantum electrodynamics using plasma-based accelerators. For…
SHARP: A compact focusing system for medical applications using a diverging plasma lens
Kyrre Ness Sjobak, Elisabeth Rød-Lindberg, Abélia Ellingsen +5
Cancer therapy for deep-seated tumors requires precise irradiation of a small target deep within the patient while minimizing radiation exposure to surrounding tissues. This can be…
ABEL: The Adaptable Beginning-to-End Linac simulation framework
J. B. B. Chen, E. Adli, P. Drobniak +6
We introduce ABEL, the Adaptable Beginning-to-End Linac simulation framework developed for agile design studies of plasma-based accelerators and colliders. ABEL's modular architect…
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…
