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…
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…
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…
Electro-Optic Sampling of Transient Fields from the passage of High-Charge Electron Bunches
M. J. Fitch, A. C. Melissinos, P. L. Colestock +3
When a relativistic electron bunch traverses a structure, strong electric fields are induced in its wake. We present measurements of the electric field as a function of time as mea…
Compression of High-Charge Electron Bunches
M. J. Fitch, A. C. Melissinos, N. Barov +3
The A0 Photoinjector at Fermilab can produce high charge (10-14 nC) electron bunches of low emittance (20 pi mm-mrad for 12 nC). We have undertaken a study of the optimal compressi…
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…
