    • The induced field data from the 30 probe array were projected onto the poloidal vector spherical harmonics of orders one through four using least squares, giving 24 Gauss coefficients: one per axisymmetric mode, two per nonzero m mode. Typical experiments consisted of increasing the applied field from ambient to the maximum external field (typically 0.20 T) in 2.2 mT increments for a fixed rotation rate.

    • note
    • The velocity measurements were obtained using pulsed ultrasound Doppler velocimetry at four MHz. Oxide particles that occur inevitably in our sodium scatter sound and track the flow [19]. We constructed an ultrasound transducer with a PTFE surface coated by a thin film of silicon rubber in order to ensure good wetting with the sodium. The chord of velocity measurements was 0.063 m below the equatorial plane and off axis by 0.043 m at the nearest point.
