Microwaves - Power Up the Particles

Typical microwave ovenThe power of a typical microwave oven is a few hundred watts. The linac klystron is capable of generating 65 Megawatts, that is 65 million watts, though only for very short pulses.

Since the accelerator began operation in 1966, the maximum energy to which it can accelerate electrons has more than doubled by improving the energy output of the klystrons.

In a microwave oven, heat is generated in the food when the electromagnetic fields of the microwaves excites (vibrates) molecules, particularly water molecules, within the food. The energy from the microwave is thus converted into heat energy in the food. At SLAC, microwaves provide energy to accelerate the electrons or positrons along the two mile accelerator structure. There is one klystron every forty feet along the gallery above the accelerator structure.

The building housing that houses the klystrons (the Klystron Gallery) is the two mile long building visible from any plane flying into San Francisco from Hawaii, or from Highway 280 on the overpass just south of Sand Hill Road.
