ITPA Avilla January 2008 © Matej Mayer Langmuir probes from outer divertor A few blisters are observed in this area of the sample
ITPA Avilla January 2008 © Matej Mayer Summary Blister-like structures are observed, but they are solid and do not contain voids No blisters A few blisters are observed in some areas of the sample Surface modifications of W due to plasma exposure are small
