After two years of operation the tokamak TFR 400 was shut down. About 50 samples of the stainless steel liner were cut out at the outer circumference and at several places on the small circumference and analyzed by elastic backscattering of 2.5 MeV protons, by ion induced X-rays and by high resolution scanning electron microscopy combined with X-ray analysis. Deposits of all materials are found which have been used for limiters and probes positioned close to the plasma boundary during the history of the machine, i.e. B, C, Mo and W. Additionally oxygen is present. On the side of the limiter upon which the ion current is incident more impurities were deposited on samples with an azimuthal position between two main toroidal coils than on samples positioned in line with the coils indicating deposition as ions. On the small circumference the deposits varied in magnitude up to a factor of ten but no systematic positional dependence was found.
