Abstract
New fabrication techniques associated with cost reduction is gaining attention in the field of superconducting (SC) accelerators. Owing to the low process temperature, cold spraying is a suitable technique to obtain SC cavities. In this work, superconducting properties of cold sprayed Niobium (Nb) is discussed and compared with other techniques. Critical temperature (Tc) for superconductivity of cold sprayed coatings were estimated to be ∼ 8.6 K as against 9.2 K for the same of bulk Nb. Residual Resistivity Ratio (RRR), critical fields (Hc1 and Hc2) were also compared. Cold spraying can be an alternate route to obtain Nb superconducting cavities.
