Abstract :
An apparatus is described to calibrate the sensitivity of several cesium clocks to temperature fluctuations. Analysis of USNO clock data has shown that control of the temperature range to within +1°C is sufficient for the attainment of an Allan deviation of a few parts in 10 14/day; cross-correlations with frequency were found only for temperature excursions that were significantly greater
