Title	76: Connection between particle and momentum transport
Name:	Saskia Mordijck smordijck@wm.edu	Affiliation:	The college of William and Mary
Research Area:	Turbulence & Transport	Presentation time:	Requested
Co-Author(s):	Ed Doyle	ITPA Joint Experiment :	Yes
Description:	Theoretical work [P.H. Diamond et al. 2009 Nucl. Fus. 2009] shows that there is a strong connection between particle transport and momentum transport. Recent experimental results on ASDEX (see IAEA McDermott) shows that density peaking depends on rotation profile. However, in these plasmas they change from ITG to TEM regimes (through linear analysis), which was shown in Cmod to strongly affect rotation profiles (bifrucation) and is strongly correlated with collisionality and density.	ITER IO Urgent Research Task :	Yes
Experimental Approach/Plan:	DIII-D is in a unique position to investigate the connection between momentum and particle transport and its relation with Te/Ti, TEM vs. ITG, density limits and collisionality (these seem to be the recurring parameters). The experiment should not only look at the changes in micro turbulence but also at the changes in macroscopic transport through perturbative techniques (gas puffs as well as beam blips).
Background:
Resource Requirements:	Counter Bean, electron and ion heating
Diagnostic Requirements:	Reflectometer and every fluctuation measurement + good CER
