  1. 54. RF system design for the CEPC main ring
    Jiyuan Zhai (IHEP)
    30/05/2017, 08:30

    CEPC is a 100 km double-ring circular electron positron collider operating at 90-240 GeV center-of-mass energy of Z-pole, WW pair production threshold and Higgs resonance. CEPC and its successor SPPC, a 100 TeV center-of-mass super proton-proton collider, will ensure the elementary particle physics a vibrant field for decades to come. To reduce the overall cost, partial double ring scheme was...

  2. 55. Update on the US decadal roadmap on SRF technology for HEP accelerators
    Sergey Belomestnykh (Fermilab)
    30/05/2017, 08:50

    Recently, the U.S. HEP community has developed a 10-year research roadmap for the accelerator RF technology. In this contribution, I present a portion of the roadmap dealing with developing superconducting RF technology for future Intensity Frontier and Energy Frontier HEP accelerators.

  3. 56. Cavity design approaches and HOM damping for FCC-ee
    Shahnam Gorgi Zadeh ( Universitaet Rostock (DE))
    30/05/2017, 09:10

    In the design study of the FCC-ee an RF cavity system is required to provide the necessary accelerating voltage for the four operating modes of the FCC-ee, i.e. Z, W, H and tt-bar. Based on the preliminary studies, a single design that can serve all four setups is not feasible. The H and tt-bar systems are two demanding cases that are characterized by high accelerating voltage of up to 10 GV....

  4. 58. Crab cavities for FCC
    Rama Calaga (CERN)
    30/05/2017, 09:30
  5. 59. Potential performance of N doping and Nb3Sn
    Samuel Elliott Posen (Department of Physics - University of Toronto)
    30/05/2017, 10:30

    Plans for FCC call for 11 GV of RF voltage for ee-tt, corresponding to ~2600 SRF cells. In this contribution, we examine recent developments in state-of-the-art SRF technology that can reduce the cost burden of this significant infrastructure. Topics of discussion include new nitrogen infusion processing for bulk niobium, progress in Nb3Sn coatings, and preparation techniques that promote flux...

  6. 60. ECR: from samples to cavities
    Anne-Marie Valente-Feliciano (Jefferson Lab)
    30/05/2017, 10:48
  7. 61. Alternative materials and coating techniques for cavities
    Katsiaryna Ilyina (CERN)
    30/05/2017, 11:06

    The high critical temperature (~18K for Nb3Sn) and very low Bardeen-Cooper-Schrieffer (BCS) surface resistance of A15 intermetallics makes them a promising category of materials alternative to niobium to be used in Superconducting Radio Frequency (SRF) cavities. Despite these benefits, the excessive brittleness of this group of materials means that they cannot be used as the bulk material in...

  8. 62. Copper electropolishing studies for the FCC-ee SC-RF cavities
    Leonel Marques Antunes Ferreira (CERN)
    30/05/2017, 11:24

    Previous experiments have demonstrated a better performance obtained for thin film Nb/Cu RF cavities on electropolished copper substrates compared to chemically polished ones. In the context of the Future Circular Collider (FCC) study, CERN is designing a new copper electropolishing facility capable of processing elliptical cavities from 1.3 GHz to 400 MHz (single cell); this facility is to...
