Objectives

  • Coordinate and monitor WP15 activities
  • Define surface preparation and treatment of substrate used for thin film deposition
  • Develop and test new coatings and techniques for superconducting RF cavities
  • Define material, thickness and structure to be deposited using various deposition techniques
  • Perform various superconductivity evaluation tests on samples of superconducting films
  • Coordinate superconducting RF evaluation in three laboratories (HZB, CERN and STFC)
  • Define characteristics of technology best able to produce superconducting film for RF cavities.
