High current encapsulated target system for radioisotope production

Abstract

Solid target systems for use with vertically oriented targets are currently used at TRIUMF for radioisotope production. In order to irradiate liquids, powders, and non-electroplatable materials using the newly developed encapsulated target, a new target system for use with horizontally oriented targets is being designed. This target station has a modular assembly consisting of a landing terminal, an irradiation chamber, a manipulator, and an actuator. Targets are pneumatically transferred between the station and the hot cells. The target is positioned in the irradiation orientation by a remotely controlled actuator, which also creates concentric coolant circuit against the back surface of the target. Additional cooling is provided by a forced flow of helium gas over the top surface of the target. This target station can also be used for irradiation of regular solid targets. The paper discusses the detailed design of this target system and the current status of the project.
