THE LASER IN VESSEL VIEWING SYSTEM (IVVS) FOR ITER: PRESENT STATUS AND NEW DEV ELOPMENTS OF THE CONTROL PROCESSING AND DATA VISUALIZATION SYTEMS

A prototype of the laser In V essel Viewing and ranging System (IVVS) was developed at ENEA laboratories in Frascati. It is based on an amplitude modulated laser radar designed to withstand the severe ITER conditions. The system is able to perform viewing and ranging of in-vessel surfaces at the same time. The system has been conceived to be radiation resistant and the most critical part of the system, the fiber optic optical encoder, has been successfully tested by SCK-CEN laboratories in Mol under gamma irradiation at 15 KGy/h up to a dose of 2.47 MGy. The paper describes the architecture of the system with details on the control, processing and data acquisition equipments.
