Rj. Hawryluk et al., PREPARATIONS FOR DEUTERIUM-TRITIUM EXPERIMENTS ON THE TOKAMAK FUSION TEST REACTOR .3., Physics of plasmas, 1(5), 1994, pp. 1560-1567
The final hardware modifications for tritium operation have been compl
eted for the Tokamak Fusion Test Reactor (TFTR) [Fusion Technol. 21, 1
324 (1992)]. These activities include preparation of the tritium gas h
andling system, installation of additional neutron shielding, conversi
on of the toroidal field coil cooling system from water to a Fluoriner
t(TM) system, modification of the vacuum system to handle tritium, pre
paration, and testing of the neutral beam system for tritium operation
and a final deuterium-deuterium (D-D) run to simulate expected deuter
ium-tritium (D-T) operation. Testing of the tritium system with low co
ncentration tritium has successfully begun. Simulation of trace and hi
gh power D-T experiments using D-D have been performed. The physics ob
jectives of D-T operation are production of almost-equal-to 10 MW of f
usion power, evaluation of confinement, and heating in deuterium-triti
um plasmas, evaluation of a-particle heating of electrons, and collect
ive effects driven by alpha particles and testing of diagnostics for c
onfined a particles. Experimental results and theoretical modeling in
support of the D-T experiments are reviewed.
