Velocity Bunching in Photo-Injectors

Abstract. We describe here a new method to increase the peak current of high brightness electron beams as those required to drive X-ray SASE FEL's, that is based on a rectilinear compressor scheme utilizing the bunching properties of slow waves. It is shown that whenever a beam, slower than the synchronous velocity, is injected into a RF wave at the zero acceleration phase and slips back in pha...

Pulse Compression via Velocity Bunching with the Llnl Thomson X-ray Source Photoinjector

We report the compression of a high brightness, relativistic electron beam to rms lengths below 300 femtoseconds using the velocity compression technique in the LLNL Thomson X-ray source photoinjector. The results are consistent with analytical and computational models of this process. The emittance evolution of the beam during compression is investigated in simulation and found to be controlla...

Direct Measurement of Sub-10 fs Relativistic Electron Beams with Ultralow Emittance.

Ultralow emittance (≤20  nm, normalized) electron beams with 10^{5} electrons per bunch are obtained by tightly focusing an ultrafast (∼100  fs) laser pulse on the cathode of a 1.6 cell radio frequency photoinjector. Taking advantage of the small initial longitudinal emittance, a downstream velocity bunching cavity is used to compress the beam to <10  fs rms bunch length. The measurement is per...

Velocity Bunching Experiment at the Neptune Laboratory

In this paper we describe the ballistic bunching compression experiment at the Neptune photoinjector at UCLA. We have compressed the beam by chirping the beam energy spectrum in a short S-band high gradient standing wave RF cavity and then letting the electrons undergo velocity compression in the subsequent rectilinear drift. Using a standard Martin Puplett interferometer for coherent transitio...
