First Mirrors Test in JET for ITER
Abstract
Metallic mirrors will be essential components of alloptical systems for plasma diagnosis in ITER. Acomprehensive First Mirror Test (FMT) has been carriedout in the JET tokamak. The exposure was followed by acharacterisation of mirrors and their carriers. The mainresults obtained by optical and surface analysis methodsare: (i) reflectivity of all tested mirrors is degradedeither by erosion with charge exchange neutrals or by theformation of thick deposits; (ii) deuterium and carbonare the main elements detected on all mirror surfaces andthe presence of beryllium is also found in several cases;(iii) thick deposits show columnar structure; (iv)bubble-like structures are detected in deposits; theirformation is a probable reason for deposits'disintegration and peeling-off; (v) the deposition inchannels in the divertor cassettes is pronounced at thevery entrance and then it sharply decreases with thedistance from the plasma, ?5-7 mm.
