Femtosecond Photocathode Electron Source*
A photocathode-based low-emittance femtosecondbunch electron source is developed in Osaka University to reveal the hidden dynamics of intricate molecular and atomic processes in materials through experimentation such as time-resolved pulse radiolysis or time-resolved electron diffraction. The transverse and longitudinal dynamics of femtosecond electron beam in the photocathode rf gun were studi...
متن کاملGeneration of amplified picosecond square pulses for low emittance electron generation in photocathode RF-GUN
Amplified square shaped picosecond pulses was generated for low emittance electron beam generation in a photocathode RF-GUN. Square shaped pulses were generated by using Ti:sapphire amplifier system in inrfared region and then converted to ultraviolet region via third harmonics generation. Generated squares shaped pulses were measeured by crosscorrelation and spectral interferometric technique ...
متن کاملPhotocathode rf gun emittance measurements using variable length laser pulses
The Gun Test Facility (GTF) at the Stanford Linear Accelerator Center (SLAC) was created to develop an appropriate injector for the proposed Linac Coherent Light Source (LCLS) at SLAC. The LCLS design requires the injector to produce a beam with at least 1 nC of charge in a 10 ps or shorter pulse with no greater than 1 -mrad normalized rms emittance. The first photoinjector under study at the G...
متن کاملFemtosecond Photocathode Electron Gun for Time- Resolved Electron Diffraction
Ultrafast time-resolved electron diffraction based on a photocathode rf electron gun is being developed in Osaka University to reveal the hidden dynamics of intricate molecular and atomic processes in materials. The photocathode rf gun generates a femtosecond-bunch electron beam by femtosecond laser driving. The transverse emittance, bunch length and energy spread were measured. The growths of ...
متن کاملDevelopment 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 ...
