An RF deflecting structure has been designed and fabricated for a transverse-to-longitudinal emittance exchange experiment at Argonne National Laboratory (ANL) [Y.-E. Sun, et al., Design study of a transverse-to-longitudinal emittance exchange proof-of-principle experiment, in: Proceedings of PAC-2007, Albuquerque, NM, USA, 2007, pp. 3441-3443]. The structure is a 1300 MHz normal conducting RF cavity consisting of three cells operating in a dipole (TM{sub 110}-like) mode. As high as 3.4 MV deflecting voltage is required for the experiment. In this paper, we present detailed RF design of the cavity, particle tracking simulations in the cavity and low power RF measurement results in comparison with numerical simulations. The cavity cell geometries (gaps in particular) are optimized to giving a zero orbit offset for particles crossing the cavity with zero-phase.
