A COOLING SYSTEM FOR RESONANCE FREQUENCY CONTROL OF ACCELERATING CAVITIES

摘要

PURPOSE: A cooling system for controlling the resonance frequency in an accelerating pipe is provided to control the opening ratio of a secondary controlling valve using the dependent variable of the opening ratio of a first controlling valve. CONSTITUTION: A pump(200) pressurizes coolant discharged from a plurality of accelerating pipes(101, 102) and supplies the pressurized coolant to a heater(300). A first controlling valve(410) is arranged at a position in which the downstream of a heater is branched to a low temperature flow path(432). A secondary active controlling valve(421) is arranged at a position in which a high temperature flowing path is branched to the accelerating pipes. A secondary passive valve(422) is arranged at a position in which the low temperature flow path is branched to the accelerating pipes. A controller(400) controls the opening ratio of the secondary active controlling valve with the dependent variable of the opening ratio of the first controlling valve.
