Experimental study of coherent synchrotron radiation in the emittance exchange line at the A0-photoinjector
Jayakar C. T. Thangaraj, R. Thurman-Keup, A. Johnson +7
Next generation accelerators will require a high current, low emittance beam with a low energy spread. Such accelerators will employ advanced beam conditioning systems such as emit…
Calculation of Asymptotic and RMS Kicks Due To Higher Order Modes in the 3.9GHz Cavity
L. Bellantoni, H. Edwards, R. Wanzenberg
FLASH plans to use a "third harmonic" (3.9GHz) superconducting cavity to compensate nonlinear distortions of the longitudinal phase space due to the sinusoidal curvature of the the…
The Flat Beam Experiment at the FNAL Photoinjector
D. Edwards, H. Edwards, N. Holtkamp +7
A technique for production of an electron beam with a high transverse emittance ratio. a "flat" beam, has been proposed by Brinkmann, Derbenev, and Floettmann.[1] The cathode of an…
First observation of the exchange of transverse and longitudinal emittances
J. Ruan, A. S. Johnson, A. H. Lumpkin +5
An experimental program to demonstrate a novel phase space manipulation in which the horizontal and longitudinal emittances of a particle beam are exchanged has been completed at t…
Upgrades of beam diagnostics in support of emittance-exchange experiments at the Fermilab A0 photoinjector
A. H. Lumpkin, A. S. Johnson, J. Ruan +4
The possibility of using electron beam phase space manipulations to support a free-electron laser accelerator design optimization has motivated our research. An on-going program de…
