โœฆ Synopsis

AC loss measurements have been made, by an electical method, on superconducting niobium samples in the form of tubes and foils. The measured losses can depend strongly on the magnetic history of the samples and characteristic flux motion waveforms are observed when losses are enhanced by the presence of trapped flux.

The normalized decay rate of a persistent current due to thermally activated flux creep is discussed theoretically for the case of a long superconducting solenoid wound with wires of superconducting tape, It is shown that the normalized decay rate of the transport current in the solenoid for the per
