National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Copper 3.9 GHz TM110 Cavity for Emittance Exchange.

DE2007915560

Publication Date	2007
Personal Author	Koeth, T. W.; Fliller, R. P.; Edwards, D. A.; Edwards, H. T.
Page Count	4
Abstract	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.
