“Klystron” is the generic name for the power amplifiers developed for use in radar and microwave devices. This was the first 100 kW Klystron ever built, a considerable technical accomplishment in itself. It was used to bounce radar beams off of the planet Venus and was able to track the planet around the Sun. The smaller 10kW Klystron could only be used when Venus approached near the Earth. The 100 kW Klystron was also used in the first radar exploration of the planet Mars. The 100 kW Klystron added significantly to our knowledge of the orbits of Venus and Mars.
