Enhancing the magnetic field gradient between two superconductors with rotational motion under a background DC field / Houbart, M (Liege U.) ; Fagnard, J-F (Liege U.) ; Harmeling, P (Liege U.) ; Dular, J (CERN) ; Dennis, A R (Cambridge U.) ; Namburi, D K (Glasgow U.) ; Durrell, J H (Cambridge U.) ; Geuzaine, C (Liege U.) ; Vanderheyden, B (Liege U.) ; Vanderbemden, P (Liege U.)
The ability of bulk high-temperature superconductors to trap magnetic flux densities up to one order of magnitude larger than the saturation magnetization of conventional ferromagnetic materials offers the prospect of generating large magnetic flux density gradients. Combining multiple superconductors, akin to assembling a Halbach array of permanent magnets, may increase the generated gradient even further. [...]

How to overcome the demagnetization of superconducting Halbach arrays? / Houbart, M (Liege U.) ; Fagnard, J-F (Liege U.) ; Dular, J (CERN) ; Dennis, A R (Cambridge U.) ; Namburi, D K (Glasgow U.) ; Durrell, J H (Cambridge U.) ; Geuzaine, C (Liege U.) ; Vanderheyden, B (Liege U.) ; Vanderbemden, P (Liege U.)
Assembling trapped-field superconducting magnets with mutually orthogonal magnetizations directions in a Halbach array configuration offers the prospect of generating both high fields and large field gradients. A major issue when assembling bulk superconductors in a Halbach array, however, consists in the alteration of the initial current density distribution during the assembly process. [...]
