  1. Euratom PPPL International Collaboration Activities J. R. Wilson Head Off-site Research Department Princeton Plasma Physics Laboratory 4th US-PRC Magnetic Fusion Collaboration Workshop Austin, Texas May 5-6, 2008

  2. Off-site Collaborations Benefit both PPPL and Host Institutions • Provide PPPL researchers with access to state of the art facilities • Particularly Tokamak Facilities • Bring PPPL research and technical experience to the Host Programs • Can provide missing ingredients to strengthen programs

  3. Collaboration Teams Support Research Initiatives • Experimentalists, Simulators and Theorists work together using PPPL facilities to explore research areas • Over half of the research staff spends some time on off-site research • Engineering and technical teams also support diagnostic and auxiliary systems

  4. Operations Support Provided to JET, EAST and KSTAR • Physics Operators • JET on regular basis • EAST, KSTAR for initial plasma operations • Heating Systems operation provided domestically and internationally • D-IIID ICRF • C-Mod ICRF and LH • JT-60U NNBI

  5. Complete Diagnostics or Components have been provided • TEXTOR • ECEI - microwave scattering • JFT2M • Thomson Scattering • LHD • Lost particle detectors • TJ-2 • GPI • JET • Spectrometers • MSE • Microwave Reflectometers • Lost Particle detector • TS Components • EAST • X-ray crystal window (in collaboration with PRC and Korea • Others from NSTX • KSTAR • Thomson Scattering design and Shutter

  6. JET Lost alpha diagnostic example of collabortive system • PPPL/ U of Colorado/JET • PPPL provided Faraday cups, cabling, integration and manned diagnostic

  7. TF Ripple loss in AT plasma Scintillator Probe results  NBI off-axis RG PNBI= 8.5 MW & 9 MW PICRF= 3.7 & 3.8 MW Tail protons <Ep> ~ 1.6 MeV and deuterons <Ed> ~ 0.8 MeV Ripple effect? No ripple Ripple: Imin / Imax = 0.5 V. Kiptily, et al., IAEA TCM Energetic Particles, October 2007

  8. Heating Systems Supplied and Supported • JET - ITER like antenna prototype • KSTAR ECH PI launcher and now high power long pulse launcher • JT60U- NNBI

  9. Energetic particle research provides paradigm for team effort • Experimentalists, Simulators and Theorists • Access to state of the art codes • Support of key diagnostics Alfven Cascade modes on JET observed by PPPL supplied reflectometer

  10. Divertor modeling for carbon migration studied on JET EDGE2D modelling of the 13C deposition from the JET experiment indicates several migration pathways including: 1.Leakage out of divertor and travel through the main chamber SOL 2.Ion migration through the PFR 3.Erosion/recycling movement along th 3eouter target 4.Neutral carbon transport through the PFR

  11. PPPL supports codes use by host institutions • TRANSP code used world-wide • Can be run on PPPL computers • Run support provided by PPPL • NOVA code available to collaborators • Wide variety of other codes available

  12. PPPL can and does provide Physics and Technical Collaboration Opportunities to the World • Benefits PPPL with access to state of the art facilities • Benefits hosts by bringing additional experience and resources to their projects • PPPL looks forward to opportunities to increase interaction with the PRC
