CAS Proceedings of the 2019 course on High Gradient Wakefield Accelerators, Sesimbra, Portugal, 11–22 March 2019

The CAS course on "High Gradient Wakefield Accelerators" is part of the so called topical CAS courses, which are intended to give during two weeks a deep understanding of simulation and modelling tools used for the design, construction and operation of accelerators. Theoretical lectures covered the fundamentals of modern algorithms and techniques as well as a review of the mathematical background and were complemented with case-studies done by the students in small groups. The individual manuscripts are collected from the lecturers and individually published under the name of the authors as preprint on arXiv. This proceedings document is a compilation of all contributions and it is available for electronic download on the website of the Cern–Accelerator–School.
