Niobium Superconducting Cavity for Radio Frequency: A Review

Abstract

Superconducting (SC) cavities are made up of superconducting material named niobium which is used in particle accelerators whose performance is limited at radio frequency. There are mainly two phenomena called Field Level Quench and Field Emission Loading Result which affects on Superconducting RF cavities. In few years, The developers are working on super conducting radio frequency technology for enhancing the cavity performance by using some surface treatment methods like Chemical polishing, high temperature treatment etc. These cavities work as superconductors whose resistance is near to 0 ? at cryogenic temperature (2K). In this paper, the performance parameters and loss mechanisms of the SCRF cavity is described.
