摘要： We study in this thesis the Characteristic Mapping (CM) framework and its application in various scientific computing problems involving transported quantities. The CM framework is a novel numerical approach for general transport equations; it consists in discretizing the deformation map generated by the transport flow instead of the transported quantities themselves. This computation yields the solution operator of the advection equation, called the characteristic map, which can then be used to transport any quantity evolving under the same transport flow. The CM method is distinguished by several unique numerical properties made possible by its geometric approach: any number of transported quantities can be simultaneously and coherently evolved using the same characteristic map, the evaluation of advected fields through map pullbacks guarantees relabelling symmetry and thus eliminates artificial viscous dissipation, the group structure of the characteristic maps can also be used to decompose long-time maps into a number of short-time submaps allowing for efficient coarse grid computations. The resulting numerical method is efficient, accurate and well-suited for multiscale problems such as the simulation of incompressible inviscid fluids. We will first motivate the CM approach from the linear advection equation. We will also study the some underlying theory and preliminaries on which the CM method is built, in particular, we will examine relevant differential calculus concepts which allow us to formulate the characteristic map as the solution operator to the Lie-advection equation. As a first application, we study the use of the CM method for the problem of equiareal surface parametrization in the context of passively advected surfaces. In this case, the CM method is used to produce a redistribution map on the parametric space which, when composed with the evolving parametrization, yields an equiareal parametrization of the surface. Next, we apply the CM method to

摘要： Niobium-3 Tin (Nb3Sn) is the most promising alternative material for Superconducting Radiofrequency (SRF) particle accelerator cavities. Current SRF accelerators use superconducting niobium accelerator cavities, which are nearing their theoretical limits of performance. Nb3Sn promises increased quality factors, twice the operational temperature (4.2 K instead of 2K), and almost twice the theoretical accelerating gradient--96 MV/m in a TESLA elliptical style cavity. These advances can reduce the size and complexity of particle accelerators while simultaneously making them more efficient. The capability of operating at 4.2 K enables the creation of small-scale superconducting accelerators that are run off cryocoolers and could be used in research and industrial applications. Current Nb3Sn cavities achieve quality factors of 2·1010 at 4.2 K. The accelerating gradient, however, is limited far below the theoretical potential of this material, with the best recorded reaching 24 MV/m. In this work we present studies on what is limiting the maximum accelerating gradients in these cavities. We study cavity performance under RF testing, make dynamic measurements of cavity heating during operation, study samples with microscopy, and develop models of Nb3Sn material growth. In the process we develop new diagnostic tools for SRF development: a dynamic/high speed temperature mapping system that measures the spatial heat distribution on a cavity at 50 ksps, and high-power test system for measuring the ultimate critical fields (theoretical limit of the accelerating gradient) of new materials. We explore models of cavity losses/heating that limit the accelerating gradient and propose modifications to the material growth process to create Nb3Sn cavities with higher accelerating gradients and quality factors. We conclude with results from a new cavity coating wherein we have suppressed multi-gap superconductivity that has been seen in these cavities and was a limitation to the quality
