The design of a gravitational antenna consisting of a relatively large piezoelectric quartz crystal cooled to 3 m /sup 0/K is presented. Calculations show that the use of the piezoelectric output to detect signals results in a simplification of the apparatus with no loss in sensitivity as compared to that attainable with similar antennas employing magnetic-displacement detectors. For both types of antennas the sensitivity is considerably better than that required to detect thermal oscillations at 3 m /sup 0/K and compares favorably with that attainable with massive room-temperature antennas.
