摘要
摘要 研究了在以 123/124I 为基础的放射性核素生产过程中冷却ТеО2 靶件的可能性。研究考虑了用于生产放射性药物的不同冷却方法及其优缺点。提出了一种新方法，即通过细分散的喷射水流冷却固体靶（TeO2 层）的正面。在托木斯克理工大学的回旋加速器上进行了用加速氘核光束冷却 TeO2 靶件的实验。结果表明，在水流速度为 15 mL/min 和喷射羽流直径为 38 mm 的条件下，113 W 的光束热能在靶表面温度为 120-130°C 时被耗散。
A New Method for Cooling a Solid Target during Iodine-123/124 Production at a Cyclotron
The possibility of cooling a ТеО2 target during production of radionuclides based on 123/124I has been investigated. Different cooling methods used in production of radiopharmaceuticals, as well as their advantages and drawbacks, are considered. A new method is proposed for cooling the front side of a solid target (a TeO2 layer) by a fine-dispersed flow of sprayed water. Experiments have been conducted at the cyclotron of the Tomsk Polytechnic University on the cooling of a TeO2 target irradiated by an accelerated deuteron beam. As a result, at a water flow rate of 15 mL/min and a spraying plume diameter of 38 mm, the beam thermal energy of 113 W has been dissipated at a target surface temperature of 120−130°C.
