For an optimally matched detector of gravitational radiation pulses, the sensitivity depends largely on the quality factor, Q, of the antenna material Although in general the Q's of many materials tend to increase at low temperatures, their temperature dependence is marked by relative minima that ca

โฆ Synopsis
The O of a large unpolished quartz crystal has been measured in the temperature interval 4-300 K and found to be similar in behaviour and magnitude to that of highly polished crystals previously studied. These results are of interest in the development of quartz crystal, gravitational, wave antennae the sensitivity of which increases in proportion with the mass. The data indicate that large raw quartz crystals are suitable for use as antennae.
