Gurnham, C.W.A. and Große, V. and Hampshire, D.P. (2020) 'Angular Jc measurements at 77 K in-field, on an ISD REBCO coated conductor using a straightforward mechanical scribing technique to reduce tape width.', Journal of Physics: Conference Series, 1559 . 012036.
E-J traces have been measured on an inclined substrate deposition coated conductor up to 0.7 T as a function of angle at 77K. A large change in Jc is seen on reversal of the direction of the magnetic field, associated with different surface barriers to flux nucleation. The effect of angular hysteresis and field hysteresis on Jc has been found to be much smaller. Narrow bridges have been successfully fabricated by a simple scribing technique using a diamond-tipped scribe and a template. These bridges have been made from 1.4 mm to 4 mm width on the 12 mm width tape, which decrease Ic linearly with width. Measurements before and after the heat treatment for strain gauge glue curing at 170 °C for 120 min have been made and confirm there is no systematic decrease in Jc.
