CONTROL SYSTEM DESIGN OF KIRAMS-13 CYCLOTRON

Cyclotron has several independent control devices. For example, cyclotron consists of the magnet power supply as like main power supply of high output, vacuum system, RF system, RF fine tuner, ion source, beam diagnostic device and cooling system. In addition, each device due to being one or several devices includes controller for control them. KIRAMS-13 cyclotron developed the first in Korea at Cyclotron Application Laboratory in KIRAMS. Controllers of KIRAMS-13 automatically communicate with each other in order to maintain the cyclotron to be the best condition. And control system of KIRAMS-13 was designed the distributed control system method in order to fast communication and protective systems. Cyclotron needs the continuous monitoring because of produce RI for several hours. Therefore control system informs operator an analysis about all input and output signal of cyclotron and current situation. And in case of providing cyclotron’s trouble, this is organized easily user-friendly control program. Each device basically uses RS-422 in order to use asynchronous communication that hardly error during communication with the main computer. In this work, we will present to improve control system based on LabVIEW program through analyzing the device control of existing cyclotron.
