Abstract

A flexible magnetic resonance spectrometer is described. Its transmission type microwave structure can be used between 50 and 150 kMc. A modified Varian magnet gives a field of 28 000 gauss, homogeneous to 3 gauss over a typical sample area. A Dewar vessel fits into the 34-in. magnet gap and permits cooling of the sample below theλ point of helium. The millimeter waves are generated by backward wave oscillators, and harmonic conversion is used for the frequency measurement and control. A modification of the spectrometer makes possible the direct measurement of line width and frequency of zero-field lines.
