Purpose and Audience
This graduate-level course covers the science fundamentals and practical engineering, manufacturing, processing, and operational aspects of the superconducting RF (SRF) cavities and systems – the state-of-the-art technology used for both pulsed and continuous wave particle acceleration. The course is intended to give a comprehensive introduction to the field for students, engineers, and physicists interested in entering this field, as well as to deepen understanding of the technology for those already exposed to some aspects of SRF science and technology
Basic knowledge of electromagnetism, microwave techniques, solid state/condensed matter physics, and mathematical methods for scientists and engineers at the senior undergraduate level.
It is the responsibility of the student to ensure that they meet the course prerequisites or have equivalent experience.
Upon completion of the course students are expected to have a clear understanding of the advantages, basic underlying physics, open questions, and domain of applicability of SRF technology, as well as state-of-the-art infrastructure and techniques required for successful implementation of SRF-based accelerators.
The course will include lectures, review sessions, and simulation exercises. Homework problems will be regularly assigned during the course, and a final exam at the end of the course will be given. Instructors and/or teaching assistants will be available for help during evening homework sessions.
The course lectures will start from an introduction to the principles of RF acceleration and a general mathematical description of microwave cavities. The phenomenon of superconductivity, and the advantages it brings for RF cavities will then be discussed in detail. In-depth coverage of principles of RF superconductivity and various types of SRF cavities used for different applications will follow. Extrinsic phenomena adversely affecting the performance will be discussed. Modern cavity manufacturing, processing, and basic measurement techniques will then be reviewed. Key steps and challenges in engineering and operating of complete SRF cryomodules (cryostats, cavities, input couplers, higher order mode couplers and loads, frequency tuners) will be fully discussed. Beam-cavity interaction issues in operation will also be presented. Overview of the recent scientific progress and outlook with of remaining challenges and promising research directions will conclude the course.
