“…Scaling FFAGs are the original type of FFAG that was first described and built in the 1950s [55]- [57]. A design study for a Neutrino Factory based solely on FFAGs for muon acceleration was completed in 2001 [32].…”

This document summarizes the work of the Accelerator Working Group (AWG) of the International Scoping Study (ISS) of a Future Neutrino Factory and Superbeam Facility. The main goal of the activity was to reach consensus on a baseline design for a Neutrino Factory complex, including proton driver parameters, choice of target, front-end design, acceleration system design, and decay ring geometry. Another goal was to explore the commonality, if any, between the proton driver for a Neutrino Factory and those for a Superbeam or Beta Beam facility. In general, the requirements for either of the latter facilities are less stringent than those for a Neutrino Factory. Here, we discuss concepts, parameters, and expected performance of the required subsystems for our chosen baseline design of a Neutrino Factory. We also give an indication of the main R&D tasks — many of which are already under way — that must be carried out to finalize facility design approaches.

“…FFAG accelerators were independently proposed by Ohkawa [3], Symon [4], and Kolomensky [5] in the 1950's and several electron accelerators were built by the Midwestern Universities Research Association (MURA) in the 1950's and 1960's as prototypes for future high energy proton accelerators [6,7,8]. The scaling FFAG, in which the tunes are constant throughout the acceleration cycle, has a vertical magnetic field in the device midplane given by…”

The fixed-field alternating-gradient (FFAG) betatron has emerged as a viable alternative to RF linacs as a source of high-energy radiation for industrial and security applications. For industrial applications, high average currents at modest relativistic electron beam energies, typically in the 5 to 10 MeV range, are desired for medical product sterilization, food irradiation and materials processing. For security applications, high power x-rays in the 3 to 20 MeV range are needed for rapid screening of cargo containers and vehicles. In a FFAG betatron, high-power output is possible due to high duty factor and fast acceleration cycle: electrons are injected and accelerated in a quasi-CW mode while being confined and focused in the fixed-field alternatinggradient lattice. The beam is accelerated via magnetic induction from a betatron core made with modern lowloss magnetic materials. Here we present the design and status of a prototype FFAG betatron, called the Radiatron, as well as future prospects for these machines.

“…with r the radius in the polar coordinate, k the constant geometrical field index, F an arbitrary azimuthal function used to represent the position of the magnets and the fringe fields, and B 0az = B az (r 0 ) [11]. This type of magnet has been successfully built for several machines in the past few decades [12][13][14][15][16][17]. In the straight sections, the vertical magnetic field B sz in the median plane produced by the combined-function magnets follows the straight scaling law B sz = B 0sz e m(x−x 0 ) F , with x the horizontal cartesian coordinate, m the constant normalized field gradient, and B 0sz = B sz (x 0 ) [18].…”

Racetrack FFAG muon decay ring for nuSTORM with triplet focusing

et al. 2018

The neutrino beam produced from muons decaying in a storage ring would be an ideal tool for precise neutrino cross section measurements and the search for sterile neutrinos due to its precisely known flavour content and spectrum. In the proposed nuSTORM facility, pions would be directly injected into a racetrack storage ring, where the circulating muon beam would be captured. In this paper we show that a muon decay ring based on a racetrack scaling FFAG (Fixed Field Alternating Gradient) with triplet focusing structures is a very promising option with potential advantages over the FODO based solution. We discuss the ring concept, machine parameters, linear optics design, beam dynamics and the injection system.
