  In recent years there has been considerable interest in exploiting the
temperature dependence of sapphire whispering gallery mode frequency to develop
a mechanically stable, high accuracy temperature sensor. Disk-resonator-based
devices have been demonstrated to measure temperature with .01 K or better
accuracy in the temperature range of 273 K to 373 K. Here we have utilized
automated data acquisition and processing to rapidly evaluate a
mechanically-stabilized sapphire whispering gallery mode resonator based on a
hollow cylinder configuration.
