چکیده
A project is underway that aims to generate attosecond pulses via high-harmonic generation in rare gases, driven by extremely short and highly intense from free-electron-laser oscillators. For this purpose, it has been planned a new photocathode RF gun, dedicated high-bunch-charge operation, will be installed at the KU-FEL (Kyoto University Free Electron Laser) oscillator facility. In study, guns with two different structures (1.6-cell 1.4-cell) were compared, perspective of exploring possibility introducing bunch-interval modulation, which important for achieving high extraction efficiency FEL oscillator. As result, was confirmed introduction bunch-phase modulation would possible only case 1.6-cell gun. After structure gun decided on, particle-tracking simulations performed, study electron-beam parameters using 1 nC bunch charge. The results showed we could obtain peak current kA without large degradation other parameters.

Over the past year Advanced Energy Systems Inc. and Brookhaven National Laboratory have undertaken a program to develop a Superconducting Photocathode Electron Gun utilizing a unique cathode concept. The cathode concept is much simpler than many other approaches and should avoid many complications which might otherwise be encountered. This cathode concept does not utilize an insert of any kind ...

One of the 21 century scientific frontiers is to explore the molecule structure transition on the femtosecond time scale. X-ray free electron laser (XFEL) is one of the tools now under development for investigating femto-second structure transition. We are proposing an alternative technique – femto-second electron diffraction based on a photocathode RF gun. We will present a design of a kHz fem...
متن کاملExperimental Studies of Photocathode Rf Gun with Laser Pulse Shaping
A technique of laser pulse shaping was developed for low-emittance electron beam generation in a photocathode RF gun. The emittance growth due to space charge and RF effects in the RF gun was experimentally investigated with square and gaussian temporal laser pulse shapes. It is found that the square pulse shaping is a useful tool for both the reduction of nonlinear space charge force and the c...

A femtosecond electron bunch is essential for the observation of ultrafast phenomena. In order to improve the time resolution of pulse radiolysis and ultrafast electron diffraction (UED), that involve the use of an ultrashort electron bunch and ultrashort light, a femtosecond photocathode RF gun was investigated experimentally. The bunch length due to space-charge and RF effects in the gun was ...
