Environmental Tests of Cesium Beam Frequency Standards at the Frequency Standards Laboratory of the Jet Propulsion Laboratory
Abstract
Tests of the effect of various environmental parameters on HP 5061B, option 004, cesium beam frequency standards have been made at the test facilities of the Frequency Standards Laboratory at JPL. These standards were on loan from the United States Naval Observatory for these tests as a part of a larger cooperative program of testing and adjustment of cesium beam frequency standards between the United States Naval Observatory, National Institute of Standards and Technology, Jet Propulsion Laboratory and the University of Ancona. The environmental parameters of interest, include humidity, ambient pressure and temperature. Marked sensitivity to humidity was found in all the standards, but the sign of frequency change vs relative humidity was not the same in all standards. The results of all the tests will be given and plans for future work under this program will be discussed.
