Glimpse into the design of MRS instrument

Autor: G. Pierrat, Anatoli Legchenko

The Magnetic Resonance Sounding method (MRS) was developed in the former USSR in the late 1970s. Nowadays, available MRS instruments are more compact and reliable, and enormous progress has been made in electronics, computers and materials. Therefore
