Abstract:

This note uses the formulation described in the note “Transit Time Equivalent Circuit for a Superconducting RF Cavity”, ESS Docs Document 294-v1 to calculate the loaded quality factor for spoke cavities and the medium beta cavities of the ESS linac. The lattice data is from the OPTIMUS lattice released on 26-July-2013. The beam current assumed is 62.5 mA.
