THERMOELECTRIC TEMPERATURE CONTROL IN AN/URQ-9 FREQUENCY STANDARD
Abstract
This effort summarizes an evaluation of 5 proposed methods for modifying the ovens of the AN/URQ-9 frequency standard and gives the design details of 1 method which was adopted for development. An analysis of the system consisting of the modified ovens and proposed regulators for maintaining temperature is included. The important features of the detail design given herein are: (1) only the crystal is maintained at 25 C + or - 0.01 C, (2) the tank circuit is maintained at 60 C + or - 2 C, (3) the modified ovens will require only 2 or 3 more watts than are required by the ovens presently used in the AN/URQ-9, and (4) only simple modifications need be made in the presently used regulator circuits to regulate the modified unit.
