Design and development of device for cooling inner conductor of coaxial cable
Sweep detector or passive spectrum analyzer provides a positive monitoring of the bandwidth of the input amplifier of a tracking receiver. Used with an oscilloscope, it provides a visual display of a microwave amplifier bandpass.
Traveling Wave Maser /TWM/ that operates at S-band frequencies is characterized by a greatly improved gain-bandwidth product with relatively low equivalent-noise temperature. Tests indicate that its performance exceeds that of any other type of S-band amplifier.
In-line, quarter-wave thermal short cools the center conductor of the signal-input coaxial transmission line to a cryogenically cooled traveling wave maser. It reduces both the thermal noise contribution of the coaxial line and the heat leak through the center conductor to the maser at 4.4 degrees K.

Apparatus makes possible proper frequency adjustment in a receiver using a pump klystron for a traveling-wave master. It incorporates a tunable overcoupled cavity with irises of appropriate size to accomplish frequency spread over the desired range and to maintain the Q of the klystron circuit at the optimum value.
