The activity investigated a novel hybrid magnetic shielding system that uses both passive and active cancelation. The design and simulations used, along with the characterisation and measurements taken on the optimised system, are summarised in the executive summary report, and described in more detail in the Final Report. This activity was divided in two main work packages: study of optimisation and magnetic shield prototype. The study of optimisation work package looked at the current limitations, simulating the already existing magnetic shield system and exploring ways of improving this system. The magnetic shield prototype work package exploited the outcomes of the previous work package and converted it into a new magnetic shielding design ready for manufacture. At the end of this, both systems were experimentally characterised and the SWaP improvements quantified.
