Final design of the ITER outer vessel steady-state magnetic sensors.

Popis výsledku v původním jazyce

The outer vessel steady-state sensors (OVSS) – a subsystem of the ITER magnetic diagnostics – willcontribute to the measurement of the plasma current, plasma-wall clearance, and local perturbationsof the magnetic flux surfaces near the wall. The diagnostic consists of a poloidal array of sixty sensorswelded to the vacuum vessel outer surface. Each OVSS contains a pair of bismuth Hall sensors with themeasurement axes parallel (in the poloidal plane) and normal to the vacuum vessel. These Hall sensorswere successfully tested in environmental conditions corresponding to those in ITER (neutron irradiation,vacuum vessel bakeout, etc.) and have proven to be capable of measuring the magnetic field up to at least±7 T. An AC analogue lock-in current spinning signal processing electronics has been developed for theOVSS to eliminate the spurious voltage due to Hall sensor manufacturing imperfections and the planarHall effect. This paper presents the final design of the OVSS diagnostic, developed jointly by the ITEROrganization and the Institute of Plasma Physics in Prague.
