Design of a New Main Injector Cavity for the Fermilab Proton Driver Era

In the design report of the Fermilab Proton Driver [1], the Main Injector (MI) needs to be upgraded to a 2 MW machine. For the Main Injector radiofrequency (rf) upgrade, R&D efforts are launched to design and build a new rf system. This paper presents the new cavity design study for the rf system. The cavity is simulated with the design code Mafia [2].
