Abstract :
A practical design of microwave quadrupole amplifier has been achieved and has given a noise temperature (double channel) of 70°K at a frequency of 2600 Mc, (as measured at the input terminal of the tube). A bandwidth of 30 Mc to a temperature of 100°K has been measured. No liquid gases are required to obtain these results. The tube has been operated on a 12 foot dish antenna in a moon echo experiment, giving an overall system temperature of 130° K. A description will be given of the construction, measurement and use of the tube.
