Abstract
This paper reports the progress made at JET-ILW on
integrating the requirements of the reference ITER
baseline scenario with normalized confinement factor of
1, at a normalized pressure of 1.8 together with
partially detached divertor whilst maintaining these
conditions over many energy confinement times. The 2.5?MA
high triangularity ELMy H-modes are studied with two
different divertor configurations with D-gas injection
and nitrogen seeding. The power load reduction with N
seeding is reported. The relationship between an increase
in energy confinement and pedestal pressure with
triangularity is investigated. The operational space of
both plasma configurations is studied together with the
ELM energy losses and stability of the pedestal of
unseeded and seeded plasmas. The achievement of
stationary plasma conditions over many energy confinement
times is also reported.
