Lately, I've wanted to build a compact source of synchrotron radiation that is accessible to researchers with size and budget constraints. So far, I've managed to outline designs of the superconducting dipole magnets that will be used to keep electrons moving in a ring path within the booster ring and storage ring. In the LINAC injector for the initial electron acceleration, what radio frequency would be best to accelerate electrons in a most efficient manner? I am currently using the LHC design report from in order to aid in my research. Any help will be appreciated.
