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

• 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

• 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

• 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

• 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

• 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

• 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

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

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

Plasma Facing Components

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

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.
