Objectives:
The main aim of this project proposal is to investigate the interplay
of SAW/DAW with DWT fluctuation spectra and explore their mutual
feedbacks via generation of ZSs. A hierarchy of different numerical
models (HAGIS/LIGKA, XHMGC, GEM, ORB5, and EUTERPE) in comparison
with analytical theory will enable the identification of energetic
transfer processes between coherent modes and turbulence in a fully
non-linear statistical context. The interaction channels and their
importance under different experimentally rele- vant conditions will be
studied in detail with the self-consistent codes, and simplified models
for the cheaper hybrid codes can be developed and applied to a larger
range of parameter space. Even further, the proposed workplan will
address the modification of EP transport by SAW/DAW on long time scales
due to the self-consistent interaction with ZSs. The theoretical
framework for such an analysis has been formulated, but it has not been
adopted so far in cases of practical interest for fusion applications.
Also, recent numerical developments have not yet been exploited and
applied to this important topic. The proposed research is certainly
novel and leverages existing NLED research activities by synergy
without overlap, shifting the focus toward the interplay of different
key processes of fluctuation induced transport in burning plasmas. In
particular, fusion-relevant high- betaconditions (or large ratios of
beta_EP/beta_thermal in present day experiments) will be in the main
focus of
this project. The results of this project will provide a detailed
theoretical under- standing of the non-linear interaction of different
types of Alfven dynamics that is crucial for the development of
predictive transport models.
In summary, the project addresses a knowledge gap concerning the
interaction of different types of fluctuation spectra in a burning
plasma as expected in ITER. The understanding and the quantification of
the fundamental processes involved will facilitate projections towards
DEMO.
