Portable, superheterodyne, ultrasonic interferometers have been constructed for use with the continuous and pulsed magnetic field facilities of the National High Magnetic Field Laboratory sites at Tallahassee, FL and Los Alamos, NM. The instrumentation operates in the frequency range from 10 to 1000 MHz and enables precise measurements of changes in the ultrasonic velocity and attenuation in solids using the pulse-echo technique. In this first of a two part article we describe a basic ultrasonic system intended for measurements in quasicontinuous fields.
