Progress and Future Directions in Brightness Electron Beam Sources*
نویسنده
چکیده
The progress of various high-brightness electron source technologies, specially laser based electron sources, such as photocathode RF gun, DC and pulsed photo-gun, and laser plasma electron source, will be reviewed. The physics processes of those sources to realize best performance are clarified according to three basic ideas. They are transverse space charge emittance compensation, space charge compensation and longitudinal emittance compensation. The major progresses and issues of photoinjector are briefly reviewed. The performance of photocathode RF gun at the Brookhaven Accelerator Test Facility (ATF) is presented.

High Brightness Electron Sources
The production of unprecedentedly high brightness electron beams is a critical aspect of many applications, from free-electron lasers to advanced accelerators. The preferred method for obtaining these beams is the radiofrequency photoinjector. The physics and technology aspects of this device are reviewed here, along prospects for future progress in high-brightness beam development.
متن کاملSynchrotron radiation sources - present capabilities and future directions.
Many of the more than 40 operational light sources around the world have achieved performance levels that exceed initial design goals. These accomplishments are reviewed, along with concepts and proposals for sources with performance levels exceeding those of present sources. These include storage rings with lower electron-beam emittance than present third-generation rings and free-electron las...

متن کاملBRIGHTNESS AND COHERENCE OF SYNCHROTRON RADIATION AND FELs∗
This paper reviews the brightness and coherence properties of radiation from storage rings and free electron lasers (FELs). Starting from the statistical optics and using mutual coherence function of the radiation field, we define the transverse and temporal coherence and modes. Spectral brightness can be represented in radiation phase-space via the Wigner function which is the Fourier transfor...
متن کاملResults from Beam Commissiong of an Srf Plug-gun Cavity Photoinjector
Superconducting rf photo-electron injectors (SRF photoinjectors) hold the promise to deliver high brightness, high average current electron beams for future light sources or other applications demanding continuous wave operation of an electron injector. This paper discusses results from beam commissioning of a hybrid SRF photoinjector based on a Pb coated plug and a Nb rf gun cavity for beam en...
