The Future Circular Collider (FCC) is the next generation particle accelerator proposed by CERN to answer lingering questions about the universe, such as matter-antimatter asymmetry and dark matter.  In circular accelerators, a stainless-steel beam screen surrounds the beam orbit, protecting the superconducting magnets from synchrotron radiation. To maintain orbit stability, the beam screen is coated with a low impedance material that preserves field quality in the vacuum chamber.  In this work, experimental techniques are developed to produce and analyse HTS coatings. In addition, a hybrid Cu-HTS coating for the FCC beam screen is studied in terms of its electromagnetic and thermomechanical performance by the means of finite elements analysis when exposed to the operating conditions of the FCC.
