  1. Metrology Milestones • Metrology Task Force • Vacuum vessel manufacture - P. Goranson • Mod. Coil Form manufacture - D. Williamson • Mod. Coil winding- S. Raftopoulos • PF and TF coil manufacture - M. Kalish (you should probably be on the task force) • Field Period Assy( VV/Mod coil/TF coil)- M. Cole • Machine Assy – M. Cole/E. Perry • Diagnostics - R.Feder • PFC's - (determining and installing monuments for future PFCs and Diagnostic mounting points and sight lines) - TBD (might make sense to combine with Diagnostics task) • Tasks • Cog. Individuals to identify metrology needs and instrumentation/software that will accomplish task. • Provide a list of metrology tasks that are to be incorporated into the manufacturing, test and inspection plan. • Metrology Task force to coordinate the Procurement of hardware and software so that costs/redundancies are eliminated (or minimized, and performance is maximized • WBS managers to incorporate metrology tasks and hardware/software purchases into budgets, schedules and WAFS. • Deadlines • August 7 – Individual areas to determine metrological needs and identify hardware/software • August 15 – Metrology Task Force to distill selections and make final decisions. • August 30 – WAFS, schedules and budgets to reflect metrology tasks & purchases • After PDR – Procurement of hardware & software as needed to R&D, prototype manufacturing and final manufacturing.

  2. Vacuum Vessel Manufacture • Provide baseline Cad model to fabricators. • Fabricator to benchmark his metrology equipment by measuring a PPPL supplied template (maybe the cast 1/10 VV model). • NCSX representative present at fabricator for measurements at key hold points (TBD during manufacturing). • NCXS to independently verify VV geometry upon receiving (need project owned metrology hardware). Incorporate into as-built model. • NCSX to install new monuments in locations to facilitate assembly on Field periods and machine.

  3. Modular Coil Manufacture • Provide baseline Cad model to fabricators. • Fabricator to benchmark his metrology equipment by measuring a PPPL supplied template (maybe the cast 1/10 VV model). • NCSX representative present at fabricator for measurements at key hold points (TBD). • NCXS to independently verify mod coil geometry upon receiving (need project owned metrology hardware). Incorporate into as-built model. • NCSX to install new monuments in locations to facilitate assembly on Field periods and machine.

  4. Modular Coil Winding • Establish benchmarks on casting to use as references for measuring the winding process. • Using local measuring devices, wind coil using shimming (as required) to locate turns in proper positions • Measure height and width of coil at critical locations. • Measure location of coil surface with respect to monuments. Incorporate into as-built model. • Install new monuments in locations to facilitate assembly into field periods and machine.

  5. PF and TF Coils Fabrication • NCSX representative present at fabricator for measurements at key hold points (TBD). • NCXS to independently verify mod coil geometry upon receiving (need project owned metrology hardware). • NCSX to install new monuments in locations to facilitate assembly on Field periods and machine.

  6. Field Period Assembly • Establish monuments on vacuum vessel, modular coil, TF coils and support structure to aid in assembly. • Using global and local positioning systems, assemble field period. • Measure height and width of coil at critical locations. • Measure location of coil surface with respect to monuments. • Install new monuments in locations to facilitate assembly on Field periods and machine. • Weld on port extensions using metrology system to ensure that position is correct. • Measure final position of VV, mod coil and TF monuments. Incorporate into as-built model.

  7. Machine Assembly • Establish monuments on field period assemblies to use as references machine assembly. • Assemble 3 field periods into complete machine. Adjust field period to achieve best plasma/magnetic conformance to specs • Measure final position field period monuments. Incorporate into as-built model.

  8. Diagnostics • Using “As-built” model and monuments, establish port axis lines. • Install monuments onto vacuum vessel inner wall corresponding to plasma midplane?

  9. Plasma Facing Components • Using the port axis lines, establish monuments to use as references for installing future PFCs.

  10. Test Cell Preparation • Establish a global coordinate system that allows the repositioning if the metrology hardware. (Arcsecond GPS is leading candidate). • Install monuments on walls, floor and ceiling to allow local positioning systems (FARO arm and Laser Tracker) to reference the global coordinate system. • Establish an “order for installation” for large components so that we minimize the blocking of sightlines required for machine assembly.
