Abstract :
Control of the plasma-wall interaction during transient events will be a critical issue in ITER. A new ITER-like wide-angle infrared and visible diagnostic, allowing to observe plasma wall interaction in the main chamber, has been installed on JET. The design and the manufacture of the diagnostic and the test results are presented. ELM interaction with the JET main chamber has been observed. ELM interaction with the walls occurs mainly on the divertor but a part of the ELMs energy impacts also on the upper and outer limiters.
