Central Control roomThe entire enormous accelerator complex of KEKB is controlled from this room. Dozens of monitors continuously display the state of the accelerator. these are also many other sub control rooms operating under the control of the central facility.
2.
Superconducting Accelerating CavitiesThe electron ring is equipped with superconducting accelerating cavities. The actual cavity itself is made from superconductor, and thus produces a high accelerating voltage. This is a triumph of the world-class High Energy Accelerator Research Organization's superconductor technology.

Cryogenic Cooling System12,000L of liquid He is stored and is used to keep the Superconducting Cavities at 4°K
4.
End of the Beam transport Line and the Injection point to the Main RingHere the beam supplied by the injector enters the ring. Using speial electromagnets with fast-varying magnetic fields, it is possible to rapidly replenish the beam stored in the ring.
5.
The Injection LinacThis powerful linear accelerator supplies a 7 billion electron-volt electron beam and a 4 billion electron-volt positron beam to the two KEKB rings. It is a multi-purpose facility which also supplies other electron accelerators at the High Energy Accelerator Research Organization.
6.
KlystronThe Klystrons are installed in the Main Rings, the Linac and the Damping ring. They generate the most powerful microwaves for the Accelerating Cavities.
7.
Normal conducting accelerating cavities (ARES)The electromagnetic field inside this cavity supplies energy to accelerate the beam. It has a special structure composed of three cavities, which was designed to withstand even the world's highest beam currents.
