Research Data Supporting "Iterative Homogenisation of Trapped Field in a Bulk HTS Solenoid with PFM"

The trapped field data following pulsed field magnetisation of a bulk HTS solenoid. The field sampled at various positions of the stack following individual pulses is provided. Five Hall sensors were placed along the central cylindrical axis of a bulk HTS solenoid constructed using four EuBCO rings. A sensor was placed in the middle of each ring, and one was placed in the middle of the stack. The magnetic field was sampled using these sensors during and after the pulse. The dataset shows the trapped field measured after each pulse. Multiple pulses were applied. The applied field is calculated from the capacitor voltage, and the coil position refers to whether the pulse coil was positioned with its centre aligned with the centre of the lowest bulk (Low), the centre of the stack (Mid), or the centre of the highest bulk (High). The 'Bz' columns show the trapped field in tesla, with the value in brackets indicating the z position of the sensor with respect to the centre of the stack, i.e. Bz(25.5) corresponds to the trapped field in the centre of the bulk ring located at the top of the stack.
