About Best Cyclotron Systems

Best Cyclotron Systems, Inc. (BCSI) has been established in Springfield, Virginia, U.S.A., for the design and production of commercial cyclotrons.  The company is a subsidiary of Best Medical International, a company renowned in the field of medical instrumentation and radiation therapy.  Cyclotrons are manufactured and tested at Best Theratronics in Ottawa, Ontario, Canada.  BCSI is currently focused on five different energy cyclotrons: the 15, 25, 30, 35 and 70 MeV negative hydrogen ion accelerators.

Cyclotron Characteristics

All Best's cyclotrons have room temperature magnets, deep valley design with four radial sectors, two dees in opposite valleys, external ion source and simultaneous beam extraction on opposite lines.  See below for an illustration of our cyclotron models.

Cyclotrons

The main characteristics of the cyclotron magnets are shown in the following table.  The 30 MeV cyclotron may be upgraded to a 35 MeV.
