Abstract
A traveling-wave maser, tunable from 14.3 to 16.3 GHz, has been completed and is ready for installation on the 64-m antenna at Goldstone Deep Space Communication Complex. The maser can provide more than 30 dB net gain at any frequency within its tuning range; an equivalent input noise temperature of 8.5 K has been measured in the laboratory. The maser is a ruby-loaded comb structure (C-axis orientation 90 deg) which operates in a closed-cycle helium refrigerator. The 8000-G magnetic field required for maser operation is supplied by a superconducting magnet. The entire package weight is 70 kg, and the unit is capable of operation in any position.
