Abstract
- The Radial X-ray Camera (RXC), as an important diagnostic system among more than one hundred ones in ITER Tokamak, is used to measure the poloidal profile of plasma X-ray emission with high spatial and temporal resolution. The automatic and safe operation of RXC will require a reliable and rugged Instrumentation and Control (I&C) system which is used to monitor and control, acquire and process data and design operation procedures. The I&C has been preliminarily designed based on ITER CODAC (COntrol, Data Access and Communication) architecture and ITER-PCDH (Plant Control Design Handbook) Journeaux, [ 1 ] guidelines since the technical understanding of CODAC technology was helpful in development of plant system I&C for RXC. The monitor and the control functions, which were implemented by Slow Controller (SC) using PLC (Programmable Logic Controller), manage the slow signals such as status of various sensors, parameters of amplifiers, temperature of detectors and health status of cubicle. Data acquisition and data processing, which were realized by Fast Controller (FC) utilizing EPICS (Experimental Physics and Industrial Control System), are responsible for collection of raw signal from detectors, data archiving, data calculation through algorithmic and publishing to PCS (Plasma Control System). A state machine was developed to coordinate the execution of operation steps of RXC. The prototype I&C system for RXC was successfully tested on Mini−CODAC.
