3. NSTX NSTX Team Meeting –Masa Ono April 25, 2014 ES&H Issues (J. Levine) NSTX-U operational preparation activity (e.g., diagnostic installation) is commencing and we need to be extra cautious regarding safety! With nice spring weather, the outdoor activities could bring hazards - Proper protective clothing (e.g., long sleeve shirts and pants) - Mindful of Ladder safety - Gloves, mask, and eye protection - Watch out for bees and other insects Safely, Safely, Safely 3

4. NSTX NSTX Team Meeting –Masa Ono April 25, 2014 NSTX-U Department Activities in Q2 FY 14 Significant collaboration research contributions are being made in diverse science areas by the NSTX-U research team. On-going active research collaboration particularly with DIII-D and EAST. Several activities resulted in IAEA synopses. A good set of IAEA synopses (~ 30) accepted by IAEA. Favorable budget should enable preparation for the NSTX-U operation while completing the Upgrade Project. Some resources maybe available to start the design work on high priority five year plan enhancements. –MG motor generator repair procurement should be concluded in the near future and the work to start in May. –Firing generators were installed. It is ready for test when the DCPS is avaiiable. –HHFW antenna should be re-installed in early May along with the P-CHERs passive plates. –In-vessel diagnostic installation/reinstallation work is in progress. NSTX-U OFES BPM visit / presentation took place on April 17, 2014. 4

5. NSTX NSTX Team Meeting –Masa Ono April 25, 2014 Formulating Strategy for Successful Implementation of FY14 Milestones Mainly Through Data Analyses, Theory/Modeling, and Collaborations

6. NSTX NSTX Team Meeting –Masa Ono April 25, 2014 FY 14 NSTX-U PEMP Notable Outcomes Goal 1.0Mission Accomplishment FES: Carry out scenario modeling and research planning to ensure a strong NSTX-U research program in FY 2015. (Objective 1.1) Part of the high priority NSTX-U research activities including enhanced modelling of NSTX-U current ramp-up by Francesca Poli (PPPL). Favorable budget helping this area of program activity. FES: Analyze experimental data from FES major facilities to investigate and quantify plasma response to non-axisymmetric (3D) mangetic fields in tokamaks, in support of the FES joint research target. (Objective 1.1) NSTX-U researchers, Jong-kyu Park (PPPL) and John Canik (ORNL) are co-leading the effort at PPPL. Goal 2.0 Design, Fabrication, Construction and Operation of Research Facilities FES: Continue to maintain the NSTX-U project with 10% of cost and schedule. (Objective 2.2) The NSTX Upgrade project is supported at the highest priority from the NSTX Program side. The preparation for operation of the NSTX-U research facility has begun by the NSTX-U engineering and research operations team. Favorable budget is helping this area of program activity. Ron Hatcher’s recent passing has created special challenges in various areas including DCPS, CHI, and ISTP. Goal 3.0 Program Management. FES: Expand engagement with university scientists to enhance the NSTX-U program. (Objective 3.2) C-Mod collaboration contract in place, but postponed at least 1 year due to C-Mod operations. Favorable budget helping fund collaborators, also holding team-wide meetings to identify ways of expanding university engagement.

8. NSTX NSTX Team Meeting –Masa Ono April 25, 2014 The NSTX Upgrade Project Team is focused on CD-4 completion in December, 2014. The NSTX-U Research Team should focus on starting in March 2015. Complete as much research run preparation tasks as possible prior to CD- 4 to minimize the period between CD4 and the research plasma operation. Assume the machine accessibility decreases as time goes on. Get your work done early!! Schedule will Provide Exciting Research Operation in FY15 18 Run-Week commitment means we must start the run in mid-March Res.
