SUMMARY:DIII-D research towards ITER and future fusion power plants\, 
 Plasma Physics (Physics/ECE/NE 922) Seminar\, Auna Moser\, General Ato
 mics
DESCRIPTION:The DIII-D National Fusion Facility is a tokamak user faci
 lity in San Diego\, operated by General Atomics for the US Department 
 of Energy. The DIII-D research program brings together universities\, 
 national laboratories\, and private companies to advance physics under
 standing and close gaps towards ITER and future fusion power plants (F
 PPs). This presentation will provide an overview of recent experimenta
 l results highlighting progress in core-edge integration\, preparation
 s for ITER and other burning plasmas\, and advances in plasma-interact
 ing technologies. Core-edge results include characterization of high-p
 ressure and -density regimes accessible with a new Shape and Volume Ri
 se divertor geometry\, high-poloidal-β scenarios\, naturally small-Ed
 ge Localized Mode (ELM) regimes\, and characterization of small-ELM fl
 uences extrapolatable to future devices. Research preparing for ITER a
 nd other burning plasmas includes demonstration of increased diagnosti
 c resolution with machine-learning techniques\, device-independent rea
 l-time radiation front control\, observation of Alfven eigenmode activ
 ity suppressing turbulence\, and characterization of runaway electrons
  in low density startup. Plasma-interacting technology advances includ
 e helicon heating and current drive\, first-of-a-kind direct measureme
 nts of runaway electron wall heating and damage\, and a survey of pote
 ntial plasma-facing materials for FPPs. Upcoming facility upgrades\, i
 ncluding a new divertor currently under installation\, will also be pr
 esented.<br>\n<br>\nThis material is based upon work supported by the 
 U.S. Department of Energy\, Office of Science\, Office of Fusion Energ
 y Sciences\, using the DIII-D National Fusion Facility\, a DOE Office 
 of Science user facility\, under Award DE-FC02-04ER54698.
