A Proposed Multi-Purpose Separated-Sector Cyclotron at IPCR

A new research facility including an accelerator complex to provide all heavy ions up to uranium has been proposed at the Institute of Physical and Chemical Research. A separated-sector cyclotron (SSC) with K=620 MeV is being designed as a booster accelerator for a variable-frequency heavy-ion linac now under construction. For the injection of relatively light ions up to neon into the above SSC, the existing ordinary cyclotron will be converted into an AVF machine with K=90 MeV to be used as another preaccelerator. The maximum beam energy provided by this accelerator system will range from 120 MeV/u for fully stripped ions to 15 MeV/u for very heavy ions such as uranium. Acceleration of light particles like deuterons and ¿ particles is also possible. The basic design and some model studies of the proposed machine are described.
