Working at Columbia University, he and graduate student James Gordon built a contraption in which a generator called a klystron, emitting radiation at microwave frequencies, excites a beam of ammonia molecules.
The electron microscope is one, the klystron, which supplies power to radar systems another.
To do so they combined the positive aspects of a magnetron (its high power output) and of a klystron tube (a device that used resonant cavities to amplify microwaves).
The beam transmitting THE DAY THE EARTH STOOD STILL is by redundant high-powered klystron amplifiers connected by a traveling waveguide to a five meter parabolic dish antenna.
I did however get cancer that looks like it might be coming back, and my lawyers say that it's probably from being exposed to ionizing radiation from working on unshielded klystron tubes that had 30,000 volts of electricity running through them and glowed eerily green, but that has yet to be proven in court.
It housed enormous banks of klystron batteries and the air seemed to vibrate with a mechanical hum.
They developed a system using a klystron to extract electricity directly from the plasma.
Varian, Sigurd Varian, and William Hansen invent the klystron tube at Stanford.
Russell and Sigurd Varian, William Hansen, and Edward Ginzton who together at Stanford in the late 1930s had developed the klystron, the first tube which could generate electromagnetic waves at microwave frequencies.
"It has safety mechanisms and it won't turn on again." klystron tube can get hot, so keep the microwave's vents clear.
