Design Study for the Accelerating Cavity of the Racetrack Microtron Eindhoven.

A 17-cell bi-periodic standing wave slot coupled structure will be used as accelerating structure for the RaceTrack Microtron Eindhoven. The numerical design of the struc-ture has been performed with the computer codes SIJPER-FISH and MAFIA. Analytical calculations for a bi-periodic accelerating structure with full end cells including direct coupling are presented. Equations giving the detuning of the chain mode frequencies for known individual cell er-rors and coupling coefficients are derived. After numerical inversion these equations will be used for the final tuning of the cavity.
