Design and Construction of a Pulsed Field‐Gradient NMR Probe for a High‐Field Superconducting Magnet

We describe the design and construction of a high‐resolution pulsed field‐gradient NMR probe for use in a high‐field superconducting magnet. Overview and details of the design and construction of the probe case, rf circuitry, temperature control and shielded gradient coils for a heteronuclear probe suitable for a spectrometer (Bruker MSL‐300) equipped with a wide bore (i.e., 89 mm) magnet (Oxford) are given. The interior of the probe is designed so mat it may be easily moved to variable height so as to accept easily various gradient coils. A design for a novel jig for the winding of saddle‐geometry rf coils is given.
