Design for a multiple target system for a medical cyclotron.
A novel target system has been designed for a compact cyclotron. The system permits one of three or more targets to be selected remotely for bombardment, permits all target and chemical operations to be controlled remotely, causes no change in beam energy or beam current, occupies a limited space, and is simple to construct and maintain. The targets are mounted to a flexible bellows-multiple port manifold assembly, supported on a fan-shaped turntable. A motor moves the system to align the target to be bombarded with the main beam axis. Designs for two subassemblies are also presented. These are a retractable target chamber for water and a remotely controlled variable collimator.
