LOW NOISE RUBY MASER AMPLIFIER

From Electron Spin Resonance studies carried out in the Basic Physics Division the parameters required for three-level maser action in a Ruby crystal were determined. To avoid the complication of using a conventional copper wire water-cooled solenoid an integral superconducting solenoid was designed. The signals were bounced off the moon using a 12ft parabolic microwave aerial.

The microwave components for amplifying were installed in a modified W.D. 2 ton trailer. The gas from the liquid helium refrigerant used to cool the maser crystal and the superconducting solenoid was collected in gas balloons manufactured at SRDE.
