Transverse to longitudinal emittance exchange beamline at the A0 photoinjector

PDF Version Also Available for Download.

Description

The FNAL A0 Photoinjector is being reconfigured to test the principle of transverse to longitudinal emittance exchange as proposed by Cornacchia and Emma, Kim and Sessler, and others. The ability to perform such an exchange could have major advantages to FELs by reducing the transverse emittance. Several schemes to carry out the exchange are possible and will be reported separately. At the Fermilab A0 Photoinjector we are constructing a beamline to demonstrate this transverse to longitudinal emittance exchange. This beamline will consist of a dogleg, a TM{sub 110} 5 cell copper cavity, and another dogleg. The beamline is designed to ... continued below

This beamline will consist of a dogleg, a TM{sub 110} 5 cell copper cavity, and another dogleg. The beamline is designed to reuse the bunch compressor dipoles of the photoinjector, along with some existing diagnostics. Beamline layout and simulations are presented. Emittance dilution effects are also discussed.
