9. Capability and Future Ideas of Polarized Beams from GaAs in DC HV Photo-guns

Joe Grames

The landscape of high energy particle physics experiments requiring polarized electron beams was forever changed by the introduction of the GaAs-based electron source to particle
accelerators. Introduced in the 1970’s to the SLAC accelerator, such a source was used to help establish the Standard Model. Since then DC high voltage polarized electron sources based on GaAs photocathodes were...

8. Recent Progress on advanced photocathode operation in SRF Guns

As well known, the quality of the photocathodes is critical for the stability and reliability of the gun operation. In last years, thanks to the developed photocathode technology, several SRF guns were successfully used for beam operation at kHz-MHz repetition rate. In this presentation, we will together view the achievements as well as open questions for the reliable SRF gun operation, and...

28. CW Normal-Conducting RF sources for future linear colliders

Normal-Conducting VHF guns provides short, stable, high repetition rate, relativistic electron pulses with transverse brightness required to drive X-Ray Free Electron Lasers. In this talk will review the current status of the technology and discuss its possible use in High Energy Physics, together with future possible R&D avenues for increased performance.

21. The First Beam of an Ultrahigh Gradient RF Photogun

Chunguang Jing (Euclid Techlabs)

High brightness electron beams are appealing for light sources, electron microscopy, and high energy collider, etc. An Ultra-high gradient on cathode is one of the most desirable parameters that improve the beam brightness. However, the maximum gradient is limited by the effects of RF breakdown in general. We present development of an X-band electron photoinjector operating in a very short RF...

19. Particle Sources for Advanced Accelerators

Matthias Fuchs

17/02/2022, 12:50

Experimental and theoretical development of particle injectors for the generation of high-brightness beams are important for future accelerators. Topics include novel methods to generate particle beams with increased efficiency, peak and average brightness, methods that will allow the manipulation of their 6D phase space distribution and novel diagnostics. This includes particle injectors that...
