A particle-in-cell model of beam dynamics in a dielectric wall accelerator
Christopher M. Lund, Paul M. Jung, Jamiel Nasser +6
Dielectric wall accelerator (DWA) technology has been proposed as a compact, cost-effective alternative to rf accelerators for proton therapy, but its beam dynamics and practical f…

Analytic descriptions of soft-edge quadrupoles for beamline design in multi-particle simulations
Aveen Mahon, Laura Miller, Ethan Cline +1
All physical quadrupoles have a fringe field falloff, giving rise to intrinsic higher order aberrations. It is especially important to consider these aberrations when designing bea…

Operational Accelerator Tuning via Model-Coupled Optics and Bayesian Steering
O. Hassan, O. Shelbaya, P. M. Jung +3
We present an on-line tuning strategy for the ISAC post-accelerator that pre-sets machine optics with a digital twin and then performs Bayesian optimization for steering under onli…
