DEVICE FOR IRRADIATING TARGETS FOR THE PRODUCTION OF MEDICAL RADIONUCLIDES ON PROTON ACCELERATORS

摘要

The invention relates to devices for the production of radioactive nuclides, namely, the means of operating a radionuclide for the production of radiopharmaceuticals used in nuclear medicine.;The technical result of the utility model is to reduce the complexity of the installation and removal of the target for its irradiation, which is achieved due to the fact that the target exchange mechanism contains a platform, in the middle part of which there is a vertical tunnel, under which a column with water is coaxial with it, while the platform is installed mounting wall to which vertical holders with coaxial holes and bearing supports for the shaft are attached, on the cylindrical surface of which there is a groove for the mounting disk to The leading sprocket located on the shaft is bolted to the shaft; on the one hand, a coupling is attached to the shaft, which is sequentially kinematically connected to a gearbox, electric motor and an electromagnetic brake, while the coupling is located in a cylindrical protective casing, which is attached to one of the vertical holders, and on the other to the gearbox, a protective casing in the form of a convex truncated cone is attached to the second vertical holder; capturing the selsyn sensor in such a way that it is located coaxially with the selsyn receiver mounted on the shaft, while the selsyn sensor is connected to an electric motor and an electromagnetic brake via a control unit, a driven sprocket mounted on the axis is mounted on the axis, the chain is attached to the target holder in the form of an L-shaped part with a vertical shelf for the target; a support is installed at the bottom of the column for the vertical shelf of the target holder so that through the target when installing it vertical shelf and the target holder held sighting axis of the proton beam.
