Self-field Effects on JC(B,T) Measurements of Nb-Ti Strands in High Magnetic Fields (2018)
Journal Article
Ridgeon, F., Raine, M., Lakrimi, M., Thomas, A., Boutboul, T., & Hampshire, D. (2018). Self-field Effects on JC(B,T) Measurements of Nb-Ti Strands in High Magnetic Fields. IEEE Transactions on Applied Superconductivity, 28(4), Article 9001805. https://doi.org/10.1109/tasc.2018.2808370

We have investigated the applied magnetic field, temperature, and self-field dependence of the critical current density of a Nb-Ti strand produced for the ITER Poloidal Field conductor. Measurements were made on a standard ITER barrel in magnetic fie... Read More about Self-field Effects on JC(B,T) Measurements of Nb-Ti Strands in High Magnetic Fields.

Superconducting Properties of Titanium alloys (Ti-64 and Ti-6242) for critical current barrels (2016)
Journal Article
Ridgeon, F., Raine, M., Halliday, D., Lakrimi, M., Thomas, A., & Hampshire, D. (2017). Superconducting Properties of Titanium alloys (Ti-64 and Ti-6242) for critical current barrels. IEEE Transactions on Applied Superconductivity, 27(4), Article 4201205. https://doi.org/10.1109/tasc.2016.2645378

We have measured the superconducting properties of the titanium alloy Ti-6Al-4V (Ti-64) as-supplied and following two of the heat treatment schedules used for the Nb3Sn strands in the ITER tokamak. The Ti-64 alloy is the standard choice in the superc... Read More about Superconducting Properties of Titanium alloys (Ti-64 and Ti-6242) for critical current barrels.

Photoluminescence of gold, copper and niobium as a function of temperature (2009)
Journal Article
Armstrong, H., Halliday, D., & Hampshire, D. (2009). Photoluminescence of gold, copper and niobium as a function of temperature. Journal of Luminescence, 129(12), 1610-1614. https://doi.org/10.1016/j.jlumin.2009.04.022

A specially constructed instrument for measuring the low intensity photoluminescence emission spectra of metals is described. It uses low luminescence optical components and dedicated sample mounting techniques. Room temperature measurements agree cl...
