  1. 4. Conduction cooled SRF photogun for UEM/UED applications
    Dr Roman Kostin (Euclid)
    11/13/20, 10:00 AM
    Applications
    Oral presentation

    The Superconducting RF (SRF) photocathode gun is a promising candidate to produce highly stable electrons for applications where a high repetition rate beam is needed. It operates in an ultrahigh Q, CW mode, and dissipates a few watts of RF power, which make it possible to achieve a 10s ppm level of beam stability by using modern RF control techniques. Euclid, in collaboration with Fermilab,...

  2. 1. Field Emission Cathodes on Niobium Conduction-Cooled SRF Cavity
    Daniel Mihalcea (Northern Illinois University)
    11/13/20, 10:20 AM
    Applications
    Oral presentation

    A high-current electron source capable of generating high charge electron bunches at MHz repetition rates is currently being prototyped. The source is based on a 650-MHz single-cell superconducting cavity modify to include a reentrant cathode holder optimized to significantly enhance the electric field on the cathode surface. The electrons are produced via field emission from a...

  3. 26. Cryocooler conduction cooled SRF cavities: experiments and compact SRF accelerator development at Fermilab
    Ram Dhuley (Fermi National Accelerator Laboratory)
    11/13/20, 10:40 AM
    Applications
    Oral presentation

    Fermilab recently demonstrated practical accelerating gradients (~6.5 MV/m cw) on a Nb$_3$Sn SRF cavity with cryocooler conduction-cooling, without using the conventional liquid helium bath. The successful integration of this cryocooling scheme with an SRF cavity is a stepping-stone for realizing compact SRF based e-beam sources for high-throughput industrial applications of electron...

  4. 16. Accelerator Stewardship with Nb3Sn at JLab
    Gigi Ciovati (Jefferson Lab)
    11/13/20, 11:05 AM
    Applications
    Oral presentation

    Jefferson Lab is funded by a grant from the DOE Accelerator Stewardship to demonstrate operation of an SRF cavity with a cryocooler to an accelerating gradient compatible with an electron energy gain of 1 MeV for possible use in an accelerator for environmental remediation. This presentation describes the current plan and initial test results on a 952 MHz single-cell cavity coated with Nb3Sn

  5. 28. Conduction Cooling Studies for 2.6 GHz Nb3Sn SRF Cavities
    Neil Stilin (Cornell University)
    11/13/20, 11:25 AM
    Applications
    Oral presentation

    A new frontier in SRF research is the use of simplified cooling methods
    that will allow easier access to SRF technology for industrial applications.
    At Cornell, we have developed a new conduction cooling setup that utilizes
    a manufactured cryocooler to provide the necessary heat dissipation for
    operation of a 2.6 GHz Nb$_3$Sn-coated SRF cavity. We report on various methods used to increase...
