We have investigated the feasibility of acceleration of a negative deuterium beam with a current of 100 µA to an
energy of 25 MeV using the AVF cyclotron in cyclotron and radioisotope center and the extraction with a stripping
foil. The simulation was performed with the code OPAL which can track particles with three-dimensional space charge.
The isochronous magnetic field was calculated with the field map of the AVF cyclotron in Takasaki advanced radiation
research institute. The current in the main coil and the position of the stripping foil was determined by searching a
reference trajectory. The transmission from the central region to the exit of the cyclotron was surveyed, changing the
initial distribution and the current.
