A copper 3.9 GHz TM110 cavity for emittance exchange

Conference ·
OSTI ID:915560
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 TM{sub 110} cavity vanishes on axis and increases linearly with transverse displacement. This 'shearing' electric field is pivotal to the exchange. The design of this TM{sub 110} 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 TM{sub 110} cavity.
