Abstract

A spectrometer was designed and constructed to facilitate measurements of T1, T2, spin echo signal‐to‐noise, and resonator quality factor, Q, between about 400 and 1000 MHz. Pulse patterns are generated at 250 MHz and mixed with the output from a second source to perform excitation and detection. A cross‐loop resonator was constructed in which the same sample could be measured in the same resonator over the full range of frequencies. An air‐core, four‐coil, water‐cooled electromagnet with a large experimental volume was built.
