  2. Research plans and needs for this year (FY2014) in preparation for NSTX-U operations in FY2015 • rtMSE • Off-line timing and latency measurements will be completed this year. Analysis software completes in a few milliseconds. • Install new computer hardware in mezzanine and integrate into existing MSE-CIF system. • Integrate rtMSE into NSTX-U control system (FY2015). • Duplication of data will be retained for the first year or two. • XP-> Windows 7 migration • Requires upgrade of LabView to v8.6 and new interface cards. We can continue to use existing National Instruments DAQ modules and chassis so long as we don’t upgrade LabView to a version higher than v8.6. • PCI facility clock card?

  3. Research plans and needs for this year (FY2014) in preparation for NSTX-U operations in FY2015 • MSE-LIF installation. • Re-installation of existing (10 sightlines) and new fibers (14 sightlines) in process now. Installation of optics table for collection optics and fiber array holder is complete. • Laser testing complete and ready for installation. • All detectors and interference filter have been received. Assembly of detector system to be completed this year. • Data acquisition system to be procured later this year. • Test cell access will be needed for spatial calibration (near term) and DNB/laser system testing (end of FY2014).

  4. Research Plans for FY2015 beyond MSE diagnostics support research in all NSTX-U TSGs. • MSE-CIF, rtMSE, and MSE-LIF will support several of the highest priority research goals highlighted in the 5 year plan, spanning several TSGs including: • 100% NI sustainment (ASC). • Transport at reduced n* and high-beta under varying q-profiles (T&T). • Understanding of non-inductive start-up and ramp-up (Start-up/Ramp-up). • MSE will diagnose the current drive/q-profile evolution from new off-axis beams (Crosscutting).

  5. Research Plans for FY2015 beyond • Fast ion modes, anomalous beam diffusion/loss effects on current profile at higher fields and from new beams (Fast ions). • RF current drive/sustainment efforts during ramp-up and low current H-modes at increased Bt (RF). • MSE-LIF will provide a non-perturbative current profile measurement for RF experiments. • The combined, fully-cross calibrated MSE systems will allow for Er measurements and better edge current density measurements, increasingly important to understand pedestal stability and transport (Boundary). • rtMSEcould possibly support feedback information useful for macro stability (Macro). • Explore new MSE-LIF capability to measure P(R).

  6. Highest-priority incremental measurement capability(For diagnostic solicitation grantees funded for 2012-2015) • Fast Filter Switching for MSE-CIF to view different beam sources in real-time. • Presently done manually, between shots. Electronic switching can be done in several milliseconds.
