Abstract
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.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
