CONTROL SYSTEM OF 10-MEV BABY CYCLOTRON

For controlling all the equipment and services required for operating the 10 MeV baby cyclotron and optimizing various parameters, an extensive control system is used. Most of the control systems are located in the control room which is situated outside the biological shield. The control console in the control room has switches for all the power supplies like main magnet, radio frequency system, vacuum system, ion-source, deflector, etc. Several Programmable Logic Controllers (PLC's) which are located near the equipment control the whole system. A technique of Supervisory Control and Data Acquisition (SCADA) is presented to monitor, control, and log actions of the PLC's on a PC through use of I/O communication interface coupled with an Open Process Control/Object Linking and Embedding [OLE] for Process Control (OPC) Server/Client architecture. In order to monitor and control different part of system, OPC data is then linked to a National Instruments (NI) LabVIEW. In this paper, details of the architecture and insight into applicability to other systems are presented.
