abstract = {In TEXTOR-93, experiments have been performed with the
upper and lower poloidal limiter blocks made of vapour
sprayed (VSP) tungsten (about 0.5 mm) deposited on graphite
with a rhenium interlayer. A series of discharge conditions
have been performed (density scan, scan of the auxiliary
heating power, radius scan). There has been found no
restriction for operation at any density with auxiliary
heating. For Ohmic conditions the same density with
testlimiters could be reached. Under siliconized conditions
no severe accumulation of tungsten in the plasma centre
could be detected. The blocks could in general stand surface
temperatures below 1700 K. Most of them survived also
temperatures above 3000 K without exfoliation. However, some
blocks showed severe damage by melting or exfoliation
probably due to insufficient contact of the tungsten layer
with the graphite. (C) 2001 Elsevier Science B.V. All rights
