SAMARA
(Superconducting Alternative Materials for Accelerating cavities and haloscope Resonators for Axions)
SAMARA aims at developing and studying superconducting materials alternative to bulk Nb with low radiofrequency (rf) and microwave (mw) surface impedance at extreme conditions: high rf fields and high dc fields. The final goal of SAMARA is twofold: the realization of high performing elliptical accelerating cavities and the test in high dc field of a Nb3Sn haloscope. To reach these ambitious goals, a fundamental part of the project is focused on the characterization of ancillary physical properties, measurement of the quantities of interest in unexplored conditions, and systematization within a coherent theoretical framework.
