High frequency response of thick REBCO coated conductors in the framework of the FCC study

A thorough microwave response study of high temperature superconductors, considered as an alternative beam screen coating, has become integral in the design decisions for CERN’s future research infrastructure. Here, we present the surface resistance Rs of various REBa2Cu3O7−x (RE = rare earth) coate...

Here, we present the surface resistance Rs of various REBa2Cu3O7−x (RE = rare earth) coated conductors available in large scale as a function of magnetic field in a broad temperature range measured by a Hakki–Coleman type resonator with resonant frequency ν≈8GHz. Analysis of the high frequency dissipation supported by DC transport characterization reveals the vortex dynamics in thick REBa2Cu3O7−x films. Determined microscopic vortex parameters span over a wide range of magnitudes and reflect the relevance of the superconducting layer’s microstructure. We demonstrate that the depinning frequencies ν0 surpass ν, which confirms the operation in high performing, low dissipation pinning regime at measurement conditions. Surface impedance extrapolation to FCC-hh conditions points towards a significant outperformance of copper by coated conductors in terms of surface resistance. The surface resistance margins would open up potential ways for a more efficient frontier circular collider.Authors acknowledge the support and samples provided by Bruker HTS GmbH, Fujikura Ltd., Sunam Co., SuperOx, SuperPower Inc. and THEVA Dünnschichttechnik GmbH.

Analysis of the high frequency dissipation supported by DC transport characterization reveals the vortex dynamics in thick REBa2Cu3O7−x films. Determined microscopic vortex parameters span over a wide range of magnitudes and reflect the relevance of the superconducting layer’s microstructure. We demonstrate that the depinning frequencies ν0 surpass ν, which confirms the operation in high performing, low dissipation pinning regime at measurement conditions. Surface impedance extrapolation to FCC-hh conditions points towards a significant outperformance of copper by coated conductors in terms of surface resistance. The surface resistance margins would open up potential ways for a more efficient frontier circular collider.
