Abstract

This thesis outlines the design and construction of an experiment to investigate dipolar interactions within a rubidium-87 (\(^8\)\(^7\)Rb) spinor Bose-Einstein condensate (BEC). For dipolar interactions to drive population transfer between the internal states of a \(^8\)\(^7\)Rb BEC the ambient magnetic field must be reduced below 100 pT. To this end I have designed an active magnetic stabilisation system which is able to reduce the ambient magnetic field to a given level with 30 nT peak-to-peak fluctuations. A design is presented for a complementary passive magnetic shield in order to further reduce the ambient magnetic field, which electromagnetic simulations show should provide a factor of >10\(^8\) reduction in the ambient magnetic field.
