| Research Abstract |
The KEK digital accelerator, which is a small scale induction synchrotron no employing any injector, has been realized, introducing the induction acceleration system into the reformed KEK 500 MeV Booster synchrotron. A He-1+beam has been accelerated from the injection energy of 200 keV to 12 MeV by induction acceleration. A permanent magnet x-band ECR ion source followed by an Einzel lens chopper capable of delivering various ion beams with a rectangular pulse profile of a desired pulse length was constructed. The ion beam is injected into the ring and captured by a pair of barrier voltage pulses and accelerated with pulse voltage pulses. These pulses are generated in induction acceleration cells. The operation of the induction acceleration system was fully maneuvered by the digital control system based on a FPGA.
