“…Two 3.9 GHz SC 9-cell cavities in a 2-3 m long cryomodule are located 13.4 m from the IP. The cavities are based on the Fermilab design for a 3.9 GHz TM 110 π-mode 13-cell cavity [194,195]. The ILC has two 9-cell versions (see Fig.…”

“…It has been proposed [1] to use the generated secondary particles, a mix of protons, pions and kaons, to perform studies of CP violation using kaon decays. After a momentum selection stage, the protons, pions and kaons have the same momentum but different velocities due to their different masses.…”

The Fermilab Main Injector can produce intense 120 GeV/c proton beams for fixed target experimentation. Two deflecting mode RF systems can be used to separate charged kaons from a momentum selected secondary beam, consisting of pions, kaons and protons, using a time of flight method. We present the RF design of a 3.9 GHz superconducting cavity which operates in the deflecting (TM110) pi-mode and the dependence of the RF parameters on the cavity shape, as determined with finite difference calculations. End cell compensation has been treated, providing cell-to-cell field flatness. First results from measurements on a prototype cavity are shown. We demonstrated that it is possible to tune the deflecting mode of a five cell cavity with bead pull measurements. Effects relating to the polarization of the modes are discussed.

A research and development program is underway to construct superconducting cavities to be used for radiofrequency separation of a Kaon beam at Fermilab. The design calls for installation of twelve 13-cell cavities operating in the 3.9 GHz transverse mode with a deflection gradient of 5 MV/m.We present the mechanical, cryogenic and vacuum design of the cavity, cryomodule, rf power coupler, cold tuner and supporting hardware. The electromagnetic design of the cavity is presented in a companion paper by Wanzenberg and McAshan [1]. The warm tuning system (for field flatness) and the vertical test system will be presented along with test results of bench measurements and cold tests on single-cell and five-cell prototypes.
