Baffle Positioning System for Thomson Scattering Diagnostic on EAST

Abstract:

A baffle positioning system has been designed to align collecting optical fibers and measure the spatial point corresponding to each fiber. In order to control field devices in both remote and local mode, two HMIs were designed with configuration software. One is for an Industrial PC in our laboratory and the other one for a portable industrial tablet deployed in EAST hall. The critical baffle mechanical actuator as well as its manual operation component was specially designed with a careful consideration of structural features of EAST device. Based on an Omron PLC, this system also provides a convenient control over several pneumatic valves and laser-spot watching lights, which are closely related to the preparation work before positioning. The trial running result shows this baffle positioning system can work stably and safely, reduce positioning time largely and bring much convenience to operator. It also has a great capability of integrating with more devices in the future.
