An apparatus is described which is suitable for measuring self-diffusion coefficients in solids using the nuclear magnetic resonance spin-echo technique employing a pulsed field gradient. The design of the probe arrangement for use at high temperature (to 1300 K) and the electronic circuit to generate the large pulses of magnetic field gradient are described in detail. The apparatus is designed for use with a pulsed NMR spectrometer assuming suitable timing pulses are available. The current switch handles 150 A, and the pulse has a fall time (to 10%) of 50 ps and produces a field gradient of 1.5 T m-1 in a quadrupole coil surrounding the high-temperature probe.
