Low power RF characterization tests of superconducting cavities at low temperature down to T = 1.8 K.
Two buried vertical cryostats (CV1 and CV2) shielded against earth magnetic field allow one to measure accelerating gradient and surface resistance of superconducting cavities. They can accommodate cavities up to Φ = 0.45 m diameter and l = 1 m long in CV1, and Φ = 0.7 m diameter and l = 1.9 m long in CV2.
