A small Nb3Ge test solenoid

Behaviour and properties of a small test solenoid made from a long piece of stabilized Nb3Ge superconductor prepared by the CVD method are described. The used CVD apparatus allows to prepare continuously pieces of more than 200 m in length. A total length of 43.5 m of the 61 m long Nb3Ge tape has been used for a construction of a test solenoid. The solenoid properties were measured in an outside magnetic field produced by 40 mm bore superconducting magnet. The contribution of the test solenoid was 0.84 T in the total magnetic field of 4.35 T and 0.42 T in the total field of 9.25 T.
