    Electron Sources
    Presentation

    Extending the charge lifetime of today’s spin polarized GaAs photoelectron guns from hundreds to thousands of Coulombs is a reasonable expectation for long-duration operation at milliampere beam current. In this presentation I will describe some of the topics frequently considered to achieve this goal, and will make quantitative comments about their proven or proposed likelihood for...

    Presentation

    Cs3Sb and related alkali antimonide compounds are high efficiency semiconductor photocathodes that can be operated with visible light and possess quantum efficiency of the order of 1-10% at green light wavelengths. Use of these photocathodes in modern linear accelerators is desirable thanks to their potential to generate high brightness electron beams. However, the ultimate brightness of a...

    Presentation

    Attaining high quantum yield, low emittance, and long lifetime from an alkali antimonide photocathode has remained a sustained focus in recent years, due especially to the need for electron beams of high average current for ERL-based electron cooling systems, synchrontron radiation sources, electron ion colliders and other applications. The ongoing development of photocathodes is motivated by...

    Electron Sources
    Presentation

    At Eindhoven university a high repetition rate thermionic injector is being built. The injector is capable of supplying electron bunches at a repetition rate of 1.5 GHz, which can be used for x-ray generation.
    The electron source generates a continuous beam with a high current and low emittance through thermionic emission. The continuous electron beam is then chopped into a pulsed beam by a...

    Electron Sources
    Presentation

    Electron cooling of ion beams employing rf-accelerated electron bunches was successfully used for the RHIC physics program in 2020 and 2021. Electron cooler LEReC uses a high-voltage photoemission electron gun with stringent requirements for beam current, beam quality, and stability. The electron gun has a photocathode with a high-power fiber laser, and a novel cathode production, transport,...

    Presentation

    High-current low-emittance CW electron beams are of great importance for the existing and future DOE facilities, medical, industrial and security applications. The CW superconducting radiofrequency (SRF) electron photoinjector is one of the most advanced, but also one of the most challenging, technologies promising to deliver such beams. While SRF technology is paving the way for future...
