Funding: Research supported by STFC grant number ST/K002503/1 "Racetrack FFAGs for medical, PRISM and energy applications". The FFAG (Fixed-Field Alternating-gradient) accelerator is a class of accelerators that comprises the best features of the cyclotron and the synchrotron, combining fixed magnetic fields with strong focusing gradients for optimal stable, low-loss operation. Here, a new type of medium-energy 1-GeV isochronous (CW) FFAG has been developed in a racetrack layout that supports two opposing synchrotron-like straights, permitting both high-gradient RF modules and efficient injection and extraction in a highly compact footprint. In this paper we present beam dynamic simulations for this compact racetrack FFAG, and compare the differences between an equivalent circular and a racetrack configuration. A comparison of the FFAG dynamics with the 800-MeV (Daeδalus) cyclotron is briefly presented. |

TUPRI013 | Dynamic Aperture Studies of the nuSTORM FFAG Ring | 1574 |
|
||
Funding: Research supported by STFC grant number ST/K002503/1 "Racetrack FFAGs for medical, PRISM and energy applications". FFAG rings with a racetrack configuration are very promising as their flexible design allow for dedicated spaces for injection/extraction, RF cavities etc. A racetrack FFAG is considered as an option for the nuSTORM facility, which aims to deliver neutrino beams produced from the decay of muons stored in a ring with long sections pointing towards detectors. In this paper we discuss the definition of dynamic aperture in these machines and use the PyZgoubi framework to compute the many turn motion in the nuSTORM ring. The roles of machine imperfections and symmetry are discussed. |

WEPRO100 | NORMA - The Normal-Conducting, Scaling Racetrack FFAG | 2198 |
|
||
Funding: Research supported by STFC grant number ST/K002503/1 "Racetrack FFAGs for medical, PRISM and energy applications". We present a design for a 30~-~350~MeV scaling racetrack FFAG accelerator for medical application - NORMA (NOrmal-conducting Racetrack Medical Accelerator) - which utilises normal-conducting magnets. NORMA consists of 12 FDF triplet cells with a maximum drift length of ∼ 2~m; an additional drift space inserted into two places forms a racetrack lattice with enough space for injection/extraction. Optimisation routines in PyZgoubi are used to find optimum cell parameters and working point. |
