A wide angle view imaging diagnostic with all reflective, in-vessel optics at JET

A new wide angle view camera system has been installed at JET in preparation for the ITER-like wall campaigns. It considerably increases the coverage of the vessel by camera observation systems and thereby helps to protect the - compared to carbon - more fragile plasma facing components from damage. The system comprises an in-vessel part with parabolic and flat mirrors and an ex-vessel part with beam splitters, lenses and cameras. The system delivered the image quality required for plasma monitoring and wall protection. (C) 2013 EURATOM. Published by Elsevier B.V. All rights reserved.
