  2. WEP contributions target characterization of [new] actuators, model validation This research will examine a variety of heating and current drive techniques in order to validate theoretical models of both the actuator performance and the transport and global stability response to varied heating and current drive deposition.

  3. NSTX-U can contribute with studies of NBIand NBI+HHFW/MHFW experiments This research will examine a variety of heating and current drive techniques... • Actuators are complementary to NBI+ECH on DIII-D • Restrict to flat-top phase • Characterization of 2nd NBI line part of FY15 Research Milestone R15-2 • Specific targets for JRT: effects of NBI parameters on q profile, rotation, *AE stability • NBI+rf scenario of interest for ITER • Unique (US) capability for NSTX-U • Look at effects on JNI (through heating -> bootstrap) • Will ITER-relevant MHFW conditions be achievable in FY15? New 2nd NBI Present NBI

  4. Model development and validation is high priority for FY13-15; excellent progress made This research will examine a variety of heating and current drive techniques in order to validate theoretical models of both the actuator performance ... • Complementary to NBI+ECH on DIII-D • Characterize new NBI line (R15-2) • Study NBI+rf scenarios • Validation of classical NUBEAM/TRANSP foreseen (R15-2) as “baseline capability” • New capabilities in NUBEAM/TRANSP will enable more accurate simulations • “Kick” model for NUBEAM being developed • Improved computation of fast ion-related quantities (e.g. JNB, torque) when instabilities are present Tests of reduced “kick” model for NUBEAM/TRANSP NSTX#139048 shaded: exp’t symbols: model

  5. Model development and validation is high priority for FY13-15; excellent progress made • Complementary to NBI+ECH on DIII-D • Characterize new NBI line (R15-2) • Study NBI+rf scenarios This research will examine a variety of heating and current drive techniques in order to validate theoretical models of both the actuator performance and the transport and global stability response to varied heating and current drive deposition. • Validation of NUBEAM/TRANSP • Validation of reduced models • Improved HHFW/MHFW modeling capabilities • Reduced models for fast ion transport by *AEs [, kinks, NTMs] being developed/validated (R14-2) • Critical Gradient (1.5D-QL) model • “Kick” model for NUBEAM • Improved models also being developed for HHFW/MHFW • Awaiting new data for extensive validation • Will apply to NBI+rf scenarios • Modeling work exploits synergy with DIII-D and collaborators

  6. Model development and validation is high priority for FY13-15; excellent progress made • Complementary to NBI+ECH on DIII-D • Characterize new NBI line • Study NBI+rf scenarios This research will examine a variety of heating and current drive techniques in order to validate theoretical models of both the actuator performance and the transport and global stability response to varied heating and current drive deposition. • Validation of NUBEAM/TRANSP • Validation of reduced models • Improved HHFW/MHFW modeling capabilities • Apply reduced models for fast ion transport • Apply improved models for NBI+HHFW/MHFW
