Abstract

Sample convection can severely attenuate the signals obsd. in pulsed field gradient spin-echo expts. such as those used for gradient shimming. A new class of pulse sequences is proposed, in which a double spin-echo refocuses the phase errors caused by sample convection, enabling gradient shimming to be performed reliably over a wide range of temps.
