Production demands at TRIUMF have pushed present target designs to the limit of their beam current capacity. A thermal analysis of the present high-current solid production targets has been carried out in order to increase radioisotope production rates through maximizing current handling capability. This paper describes the optimization of a 5° incident angle solid target for radioisotope production in service on the TRIUMF TR-30 cyclotron. Target materials compared include silver and Glidcop®,1 a dispersion-strengthened copper composite. A summary of comparative results is presented.
