Hydrogen Maser Research and Development at Sigma Tau Standards and Tests of Sigma Tau Masers at the Naval Research Laboratory

Abstract

Two hydrogen masers of the active oscillator type using automatic cavity stabilization, but without active feedback gain, were designed, built and tested by Sigma Tau Standards for the Naval Research Laboratory (NRL). The masers were tested at Sigma Tau Standards prior to shipment and again at the NRL for a period of ten weeks following delivery. In addition, Sigma Tau has modified a Small Hydrogen Maser previously built to operate with cavity feedback to become an oscillating maser without feedback.
