Abstract
Trace amounts of tritium (1-5% of the deuterium content) have been
introduced in short puffs ( 40 ms) into the low-field mid plane edge
of steady-state deuterium plasmas in JET . The transport properties of the edge
and core plasma, and the time evolution of the fraction of tritium in
recycling flux, determine the evolution in space and time of the 14 MeV
neutron emission following these puffs. Earlier work on TFTR has been in
transient, high performance plasmas. The JET experiments offered a unique
opportunity to perform measurements of fuel ion transport in an ITER relevant
regime. The main objective of these trace tritium transport experiments was to
apply the dimensionless parameter approach, used in the study of
energy confinement , to particle transport and to connect particle and
energy transport in the same data set.
