Femto-seconds Electron Beam Diffraction Using a Photocathode Rf Gun*

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...

Wake "eld of electron beam accelerated in a RF-gun of free electron laser `ELSAa

Wake "eld e!ects driven by a coasting relativistic charged particle beam have been studied for various cavity geometries. In the particular case of a cylindrical `pill-boxa cavity, an analytical expression of the (E, B)(x, t) map has been obtained as a development on the complete base cavity normal modes. We extend this method to the case of an accelerated beam, which leaves the downstream face...

Electron Gun Beam Extraction with Mosfets

Electron beams with an energy range of 10keV at 2A requiring intensity modulation with bandwidth from 50kHz 7.5MHz pose an interesting problem to the RF designer. Driving the extraction electrode of an electron gun can be a challenge with these requirements. The straight forward approach is the construction of a vacuum tube, single ended amplifier capable of delivering the anode voltage to the ...

Development of a Novel Superconducting Rf Photocathode Electron Gun

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 ...

Beam Generation from a 500kv Dc Photoemission Electron Gun*

The next generation light sources such as energy recovery linac (ERL) light sources and X-ray FEL oscillator require high brightness electron gun with megahertz repetition rate. We have developed a DC photoemission electron gun at JAEA for the Japanese ERL light source project. This DC gun employs a segmented insulator with guard rings to protect the insulator from field emission generated from...
