【 摘 要 】

An experiment is being developed at the FNAL Photoinjector Lab to demonstrate the exchange of longitudinal emittance with a transverse horizontal emittance. The longitudinal electric field of a TM110 cavity vanishes on axis and increases linearly with transverse displacement. This shearing electric field is pivotal to the exchange. The design of this TM110 cavity is a variant of the Fermilab 3.9 GHz superconducting deflecting mode cavity; however, the cavity was constructed of OFHC copper. The authors report on the construction, field flatness, polarization and high power testing of a TM110 cavity.
