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 presenc
An apparatus is described which can measure continuous alternating current losses on superconductor samples, or other heat loads, by, the calorimetric helium boil-off technique over a range of 10 mW to 50 VV. This apparatus has a modular design and is easily constructed from commercially available c
