“…More recently, the determination of the binding énergies associated with different sites, which control the jump frequency, has enabled intergranular diffusion paths to be predicted [62][63]. The jump efficiency appears to be independent of the type of boundary [63], but for a given misorientation, differs according to the orientation of the boundary plane [60], in agreement with previous experiments [61].…”

2014 De tout temps, les utilisateurs des matériaux ont tenté de contrôler leurs microstructures dans le but de leur conférer des propriétés spécifiques pour un emploi donné. C'est de ce point de vue que cet article de synthèse considère les joints de grains, éléments fondamentaux de la microstructure polycristalline, avec deux objectifs : a) tenter d'élucider les relations entre la cristallographie d'un joint de grains, qui détermine sa structure, et différentes propriétés de ce joint ; b) établir la distribution des joints de grains dans un polycristal selon leurs caractéristiques géométriques afin de comprendre leur contribution aux propriétés de l'ensemble polycristallin.Abstract. 2014 It has long been a major preoccupation of materials users, whether implied or explicit, to tailor microstructures in order to adapt specific properties for a given application. In this context, the principal aim of the present review article is to consider the fundamental elements of polycrystal microstructures, i.e. the grain boundaries. The paper discusses current understanding of two important aspects : a) the possible relationships between the geometry of a grain boundary, which determines its structure, and its various properties ; b) the distribution of geometrical characteristics, which for real boundaries can only be approached experimentally, in an endeavour to determine the intergranular contribution to the overall properties of a polycrystal.

“…To accomplish this, magnetic fields that were highly nonlinear [64] were utilized. Unfortunately, the resulting dynamic aperture was insufficient to accelerate a Neutrino Factory muon beam [65,66]. The lattice was very sensitive to the precise shape of the magnet end fields; this likely arose from the high degree of nonlinearity in the lattice.…”

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.

“…There are clearly benefits to either design. Unfortunately, to this point none of these designs have had sufficient dynamic aperture for muon acceleration [32]. In fact, one can demonstrate that it is not a large benefit in reducing the time of flight variation below what it naturally has for a linear nonscaling FFAG [33].…”

Abstract. A number of accelerator-based facilities have been proposed for the creation of neutrino beams: superbeams, neutrino factories, and beta beams. Fixed field alternating gradient accelerators (FFAGs) have potential uses in all of these facilities. Superbeams and neutrino factories require high power proton drivers for the production of pions; FFAGs can beneficial for accelerating protons for those machines. FFAGs can reduce the cost of accelerating muons in a neutrino factory because they enable the muons to make many passes through the RF cavities and still accelerate rapidly. FFAGs have potential uses in production of radioactive ions for a beta beam facility, since radioactive ions that decay into high energy neutrinos in their rest frame may potentially be produced in a ring, and the large energy acceptance of an FFAG may be useful for maximizing beam lifetime in such a ring. Finally, FFAGs have been contemplated for use in ionization cooling rings for neutrino factories, since the equilibrium distribution in ionization cooling has a large energy spread for which an FFAG's large energy acceptance is needed, and FFAGs may make it feasible to inject and extract from such a ring.

6-D Beam Dynamics in an Isochronous FFAG Ring

Abstract: Numerical ray-tracing tools for 6-D tracking in FFAG accelerators have been developed. They are applied to the simulation of muon acceleration in the newly introduced isochronous type of FFAG ring designed for 16-turn, 8 to 20 GeV muon acceleration in the Neutrino Factory.
