AbstractAbstract
[en] A new sample transfer and analysis station, incorporating modular design features, is utilized in an initial series of studies of surface deposits produced by tokamak discharges in Doublet III. A functional description of the new apparatus is given in addition to a summary of the results of semi-quantative Auger analysis of surface deposits formed over the course of a 350 discharge period of tokamak operation, during which time Ti gettering was first employed. Excluding Ti, the deposit density can be inferred to be approx.2.3 x 1014 atoms cm-2 per discharge and to consist primarily of C, Ni, and O, in order of decreasing percentage. This is more than a factor of 2 less than the amount of deposition observed prior to the advent of gettering. The dominant plasma impurity radiation is associated with O
