Current supply for high-Tc superconductor testing

January 18, 1990
Author(s)
Loren F. Goodrich, S L. Bray
Precise and accurate measurements of the DC critical current of high-Tc superconductors often require a current supply that has high input-to-output isolation, high isolation from ground and low output ripple. Also, to ensure precise current control, the

High Tc superconductors and critical current measurement*

January 17, 1990
Author(s)
Loren F. Goodrich, S L. Bray
With the introduction of high Tc superconductors, a number of problems associated with critical current, Ic, measurement have arisen. THe existing Ic measurement practices were developed and proved for low Tc superconductors. There are substantial
