DEVICE FOR MAINTAINING LOW TEMPERATURES OF PLURALITY OF SINGLE SPOKE-TYPE ACCELERATING TUBES OF HEAVY ION ACCELERATOR

摘要

The present invention provides a device for maintaining low temperatures of a plurality of single spoke-type accelerating tubes of a heavy ion accelerator. The device comprises: a vacuum vessel configured to maintain the interior thereof in a vacuum state by means of a vacuum pump connected to one side surface thereof; a pipe housing provided on the upper side of the vacuum vessel; a plurality of single spoke-type accelerating tubes installed inside the vacuum vessel by a support frame to be spaced from each other, each single spoke-type accelerating tube comprising an inner tube, which maintains a vacuum state, and an outer tube, into which a low-temperature fluid for performance testing is injected, and the single spoke-type accelerating tubes increasing the rate of acceleration of heavy ion beams; a pipe module installed inside the pipe housing so as to provide each of the plurality of single spoke-type accelerating tubes with the fluid for performance testing; and a support module connected to the pipe housing so as to support the plurality of single spoke-type accelerating tubes and the pipe module, wherein the vacuum pump is connected to each of the plurality of single spoke-type accelerating tubes, and a tuner is installed on the outer peripheral surface of each of the plurality of single spoke-type accelerating tubes so as to prevent elastic deformation from occurring due to an external pressure.
