Abstract

The Future Circular Hadron Collider (FCC-hh) is one of the most ambitious colliders ever planned to be built. The baseline design of the beam screen uses Cu, however the resistive wall impedance might be in the limit to ensure stable operation. To lower this impedance, High-Temperature Superconductors have been considered as alternatives to Cu. Employing measured surface impedance of the REBCO-CCs, the calculated resistive wall beam impedance of a hybrid REBCO-CC-Cu beam screen has shown significant improvement compared to the baseline design made of Cu.
