  The Inner First Wall (IFW) is the main limiter in Tore Supra for long and
powerful discharges. The original graphite IFW was partly damaged by 8 years of
operation and a sector of 60{\textdegree} was replaced between 1995 and 1997 by
CFC brazed elements. They are designed to accept twice as much flux (2
MW/m${}^2$) as the older ones and are expected to be more resilient. The new
elements gave the opportunity to install diagnostics (thermocouples and
langmuir probes) on a poloidal sector, to characterise the behaviour of the new
IFW and especially the heat flux profile. The pattern doesn't follow the cosine
law and is governed by strong perpendicular heat flux and abnormal deposition
at the contact point between the limiter and the plasma. The most energetic
shots of the last campaign showed that the IFW could be loaded with twice the
power deposited during these shots.
