A derivation of Maxwell’s equations using the Heaviside notation (2018)
Journal Article
Hampshire, D. (2018). A derivation of Maxwell’s equations using the Heaviside notation. Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 367(2134), Article 20170447. https://doi.org/10.1098/rsta.2017.0447

Maxwell's four differential equations describing electromagnetism are among the most famous equations in science. Feynman said that they provide four of the seven fundamental laws of classical physics. In this paper, we derive Maxwell's equations usi...

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.

The Cause of ‘Weak-Link’ Grain Boundary Behaviour in Polycrystalline Bi2Sr2CaCu2O8 and Bi2Sr2Ca2Cu3O10 Superconductors (2018)
Journal Article
Wang, G., Raine, M. J., & Hampshire, D. P. (2018). The Cause of ‘Weak-Link’ Grain Boundary Behaviour in Polycrystalline Bi2Sr2CaCu2O8 and Bi2Sr2Ca2Cu3O10 Superconductors. Superconductor Science and Technology, 31(2), Article 024001. https://doi.org/10.1088/1361-6668/aaa1b8

The detrimental effects of grain boundaries have long been considered responsible for the low critical current densities (J_c) in high temperature superconductors. In this paper, we apply the quantitative approach used to identify the cause of the 'w...

Biaxial Strain Measurements of Jc on a (RE)BCO Coated Conductor (2018)
Journal Article
Greenwood, J. R., Surrey, E., & Hampshire, D. P. (2018). Biaxial Strain Measurements of Jc on a (RE)BCO Coated Conductor. IEEE Transactions on Applied Superconductivity, 28(4), Article 8400705. https://doi.org/10.1109/tasc.2018.2793282

For several years it has been possible to measure the uniaxial strain dependence of the critical current density JC (ε) of (RE)BCO coated conductors [(RE)BCO tapes] and a parabolic strain dependence of JC (ε) has been observed. To improve our underst... Read More about Biaxial Strain Measurements of Jc on a (RE)BCO Coated Conductor.
