123I is radiopharmaceuticals to diagnose thyroid cancer and can be obtained through nuclear reaction by irradiating proton beam (30MeV, 100uA) onto 124Xe gas target in order to produce this medicine. More medicine can be produced under the same condition by irradiation of higher beam current in nuclear reaction energy. However, the higher the beam current is, the more heat is generated and target device may melt. This paper predicts whether production is possible at a higher beam current through heat analysis with modeling of 124Xe target device which is gas target. Geometrical structure modeling was used by 3D CAD SolidWorks and analyzed by using COMSOL. We used modeling in spiral way which is a more spacious surface to increase cooling efficiency of cooling water. We analyzed by simulation that target isn’t melted when the beam output of cyclotron 30 is irradiated onto gas target.
