RF Superconductivity for Accelerators

Instructors:

Hasan Padamsee and Jens Knobloch, Cornell University


The course will introduce the basic concepts of microwave cavities for accelerators and the fundamentals of RF superconductivity. In the second part we cover observed behavior, such as residual resistance, thermal breakdown and field emission - together with the underlying causes. An important segment of the course covers technological aspects such as cavity fabrication, tuning, surface treatment, clean-room environments, niobium purification and thermometry diagnostics. Throughout the course, students will use this information and computer codes to arrive at an optimum cavity design for a specific accelerator application. Finally we will cover related components such as input couplers and higher order mode dampers. Examples will be drawn from operating accelerators as well as future facilities planned for the high-current and high-energy frontiers. Prerequisites: A course in Electromagnetism.
