Nuclear spin pulse apparatus

Abstract

A detailed description including circuits and operating instructions, is given for the construction of a nuclear spin pulse apparatus which will measure nuclear spin-lattice relaxation times from 500 μs upwards and nuclear spin-spin relaxation times from 20 μs upwards over the temperature range -180° C to 220° C with an accuracy of better than ±5%. An Appendix lists where all published circuit diagrams and technical data suitable for spin echo apparatus may be found.
