Metrology milestones l.jpg

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.


Vacuum vessel manufacture l.jpg

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.


Modular coil manufacture l.jpg

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.


Modular coil winding l.jpg

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.


Pf and tf coils fabrication l.jpg

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.


Field period assembly l.jpg

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.


Machine assembly l.jpg

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.


Diagnostics l.jpg

Diagnostics

  • Using “As-built” model and monuments, establish port axis lines.

  • Install monuments onto vacuum vessel inner wall corresponding to plasma midplane?


Plasma facing components l.jpg

Plasma Facing Components

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


Test cell preparation l.jpg

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.
