摘要：
We describe an actively shielded cylindrical RF transmit coil producing a highly uniform internal field (+/- 0.5%) over an extended volume and a strongly suppressed (divided by 20) external field. Direct field mapping and experimental checks using in-situ NMR and MRI of polarised He-3 at low temperature demonstrate performance consistent with numerical field computations.
