Modelling of the radioactive ion beam (RIB) targets at TRIUMF has suggested that rotating the high energy proton beam in a circle on the face of the target may provide a greater source of radioactive ions than a static incident beam. To explore this idea a system has been configured to allow the beam of protons in the primary beamline to be steered in a circle and to permit various parameters to be changed. A description of the system and initial experience in operating the rotating beam are included.
