KEKB, KEK B-Factory, is an asymmetric energy, tworing, electron-positron collider for B-physics, and is now under construction at KEK. Machine study done at the accumulation ring, AR, of TRISTAN, in 1996 showed that HOM-free normal-conducting cavities, called ARES, and superconducting, single-cell, single-mode cavities being developed could be used for KEKB. Fast beam-ion instability was also studied experimentally. Installation of equipment in the tunnel started in February 1997. Commissioning
