Superconductor magnesium diboride is considered one of the viable materials to substitute niobium for superconducting radio frequency cavities. A MgB2 coating on the inner wall of a copper cavity will allow operation at higher temperatures (20?25 K) than Nb cavities due to the high transition temperature of MgB2 (39 K) and the high thermal conductivity of Cu. In this experiment, the goal is MgB2 coating on Cu tubes with similar dimensions to a 3 GHz cavity, as the first step towards coating the actual cavity, using the hybrid physical chemical vapor deposition technique. The results show successful coating of a uniform MgB2 layer on the inner wall of the Cu tubes with Tc as high as 37 K (Wenura K. Withanage, N. H. Lee, Sashank V. Penmatsa, M. A. Wolak, A. Nassiri, and X. X. Xi 2017).
