A 300–600 MeV scaling fixed-field alternating gradient (FFA) ring is proposed as a multipurpose proton driver for the China Spallation Neutron Source (CSNS) Phase-II upgrade under strict engineering constraints ($R_0 = 12\text{ m}$, radial beam excursion $\Delta r \le 0.8\text{ m}$, and peak field $B \le 1.66\text{ T}$). To overcome these tight boundaries, a global statistical design framework...

Invited Talk

From emittance-reduction in synchrotrons to beam delivery systems for particle therapy: a wide range of accelerator applications require achromatic beamlines, even though further constraints differ greatly between the use cases. We present a computational methodology based on multi-bend achromat and fixed field accelerator principles for the design and optimization of compact achromatic...
