Material selection for TFTR limiters
The requirements for the material to be used as the first surface of limiters in TFTR are that it: (1) withstand a heat flux of 1 kw/cm/sup 2/ for a pulse length of 1.5s and a duty cycle of 1/200 for 10/sup 5/ cycles, (2) withstand the thermal and electro-magnetic loads from 10/sup 4/ plasma current disruptions lasting about 200 ..mu..s, (3) generate impurities at a rate low enough to meet impurity control requirements (which depend on the atomic number of the material) for TFTR, and (4) have tritium retention characteristics consistent with tritium inventory requirements for TFTR. An extensive set of material tests using electron beams, neutral beams, and plasma bombardment have been carried out to identify materials which can meet the thermal requirements of the above.
