NSTX-U NSTX-U Collaboration Status and Plans - April / May 2014

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?

NSTX-U NSTX-U Collaboration Status and Plans - April / May 2014

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).

Research Plans for FY2015 beyond

• 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).

MSE diagnostics support research in all NSTX-U TSGs.

NSTX-U NSTX-U Collaboration Status and Plans - April / May 2014

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).

– rtMSE could possibly support feedback information useful for macro

stability (Macro).

– Explore new MSE-LIF capability to measure P(R).

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.
