Title 145: Resolve impact of mode spectrum on particle transport regimes with RMP
Name:Oliver Schmitz () Affiliation:FZ Juelich
Research Area:ELM Control & Pedestal Physics Presentation time: Not requested
Co-Author(s): tbd
Description: If ID 141 and ID 143 will be succesfull it is desirable to analyze the impact of changing the toroidal base mode number to n=2,1 on the transport regimes. This is of particular interest as in these base modes the ELMs were not supressed in ELM control experiments of R. Buttery last year.
Experimental Approach/Plan: Do the same scan/approach as described in ID 143 but with n=2 and n=1 and different EF mixture.
If here the tranbsport can be controlled successfully go back to the pol. div settings and apply findings for ELM control with n=1 external and n=2 fields.
Background: see ID 141 and ID 143. DIII-D has the unique capability to study the internal n=3 and the externall/internal n=2 and n=1 mixtures of RMP and EF. This is used here.
Resource Requirements: same as ID 143
Diagnostic Requirements: same as ID 143
Analysis Requirements: same as ID 143
Other Requirements: --
