RF Superconductivity for Accelerators
Hasan Padamsee and Jens Knobloch, Cornell University
The course will introduce the basic concepts of microwave cavities for accelerators, the elements 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 environments, niobium purification and thermometry diagnostics. 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.
