Abstract: The TESLA linear Collider would rely on superconducting structures at 1,3 GHz with a gradient of 25 MV/m and an unloaded quality factor at temperatures of 2 K.
However Nb Technology asks for superfluid e cooling systems. The use of a higher critical temperature superconductors would allow to adopt the simpler 4,2 K cryogenics.
V3Si has a reported Tc value of 17 K and RRR values up to 80 …. it follows –>
