The accelerator automatically operates the control. The operating accelerator must operate in sequence and the interlock protection system will function immediately in the event of a misoperation. The general control of the accelerator is to arrange the interlocking protection of each subsystem reasonably so that they can meet the requirements of the accelerator operation specifications. When the accelerator is turned on, the next operation will not work until the current operation step meets the predetermined requirements.For example, the equipment that needs to be cooled by water cannot be started before the water is supplied. When the cooling water is cut off,even if the equipment is already in operation, the equipment will stop running and the operations followed will be invalid. These control procedures are incorporated into the computer control program to automatically handle the whole operation of the accelerator from preparation to normal operation.
