The digital accelerator (DA), which is a small-scale induction synchrotron "*" requiring no high-energy injector and capable of providing various ions, was constructed at KEK"**". Beam commissioning has been carried out. The KEK-DA consists of a 200 kV high voltage terminal, in which a permanent mag. x-band ECRIS is embedded, 15 m long LEBT, ES injection kicker, and a 10 Hz rapid cycle synchrotron equipped with the induction acceleration system. An ion pulse chopped in 5 micro-sec by the newly developed Marx generator driven Einzel lens chopper"***" was guided through the LEBT and injected by the kicker in one turn. 3 micro-sec ion pulse was successfully captured with a pair of barrier voltage-pulses of 2 kV and accelerated up to 12 MeV with another flat induction-acceleration voltage-pulse through an acceleration period of 50 msec. Beam commissioning started with a He¹⁺ ion beam of 100 microA. Details of fully digital-controlled barrier bucket trapping and induction acceleration are described, although the acceleration/extraction is still at a preliminary stage. Some of unique applications, such as laboratory space science using virtual cosmic rays, will be introduced.
