Abstract
An ovenized oscillator having a temperature sensitive section of an oscillator and a heater supported in a chamber within an enclosure having an insulating gas surrounding the oscillator section and heater. Insulating walls may be added within the chamber to reduce convective heat loss through the gas. These walls form cavities around the oscillator section and are separated from each other except for small vent holes to equilibrate the pressure between cavities.
