摘要：

In this paper the Laser Induced Breakdown Spectroscopy (LIBS) measurement of the deuterium (used as a proxy for tritium) retained in and the surface elemental composition of the FTU Mo (TZM) toroidal limiter tiles, carried out from remote (similar to 2.5 m) during short breaks of the operations or during machine maintenance, are reported. Single pulse technique has been used with the FTU vessel under high vacuum or in Nitrogen or Argon atmosphere. In vacuum experiments D-alpha and H-alpha lines have been detected with good resolution, while in Ar atmosphere (5 x 10(4) Pa) the two lines were partially overlapped due to Stark broadening. First results of measurements in N-2 atmosphere (10(5) Pa)showed no presence of D-alpha and H-alpha lines. These measurements were also carried out for supporting the foreseen use of a robotic arm for an extended LIBS analysis of retained deuterium in the FTU vessel components.
