چکیده

A photoinjector is being constructed in order to produce a pulse train of up to 800 electron bunches, each with 8 nC of charge and a 3.5 ps rms bunch length. The spacing between bunches within a train is 1 s and the train repetition rate is 1–10 Hz. The desired transverse emittance is <20 mm mrad. An rf photo-gun delivers a bunched 4–5 MeV beam which will be accelerated to 14–18 MeV by a 9cell superconducting cavity and compressed magnetically. Measurements have been done on the beam delivered by a first prototype rf gun; installation of a new rf gun, the 9-cell cavity, and the bunch compressor is in progress.

Beam Test of a Superconducting Cavity for the Fermilab High-brightness Electron Photo-injector

An electron photo-injector facility has been constructed at Fermilab for the purpose of providing a 14–18 MeV electron beam with high charge per bunch (8 nC), short bunch length (1 mm RMS), and small transverse emittance [1]. The facility was used to commission a second-generation photo-cathode RF gun for the TeSLA Test Facility (TTF) Linac at DESY [2, 3]; in the future, the Fermilab electron b...

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...

Commissioning of the UCLA PEGASUS Photoinjector Laboratory

The PEGASUS Photoinjector has been commissioned at UCLA. The Plane Wave Transformer Photoinjector provides a high-brightness 17 MeV beam that will be used for numerous beam-radiation studies. Some of these will include SASE FEL, transition radiation from non-standard surfaces, and monochromatic x-ray production via PXR and Thompson scattering.

Improvement in the laser system for the A0 TTF Photoinjector

The production of high charge and high brightness electron beams places increasingly challenging demands on the drive laser used at the A0 photoinjector in the Fermilab. The IR and UV laser pulse lengths need to be optimized for such purpose. We have experimentally investigated two different ways to change the UV laser pulse length on the cathode; either by changing the bandwidth of the oscilla...

Production and synchronization of electron beams from RF photoinjector/compressor systems for ultra-fast applications

The RF photoinjector, when coupled with a magnetic pulse compression system, is now a ubiquitous tool for production of sub-picosecond electron beam pulses which are to be used in advanced accelerator and light source experiments. As the time-scale for both pulse lengths and synchronization to external systems approaches the femtosecond level, a clear understanding of the longitudunal dynamics ...
