1. B2 Casting Measurement Comparison The Verisurf data from MTM and the Romer Arm data from PPL were both filtered thru a common sorting program (sortdata2.f) to make sure we comparing similar point locations Point xyz coordinates were mapped to a “curvalinear” coordinate system tied to the B coil geometry: –X is radial distance (ie normal to base, +toward plasma) from the ideal current center –Y is lateral distance (ie normal to septum, + toward A side) –Z is the poloidal location (0 to 1) along coil winding center curve Clamp locations are identified in ProE by this parametric number

2. MTM B2 Casting Verisurf Points Translated into Clamp Local Coordinate Systems Note: All points lie within +/- 0.030” of Clamp Centerline x y Side B Side A SeptumBase Intent is Only to Highlight Clustering Of Points

3. Earlier MTM C3 Casting Verisurf Points without use of CMM? Translated into Clamp Local Coordinate Systems Note: Points Not at Clamp Centerlines x y Side B Side A SeptumBase Intent is Only to Highlight Clustering Of Points

4. PPL B2 Casting Romer Arm Projected Points Translated into Clamp Local Coordinate Systems x y Side B Side A SeptumBase Note: Data is Actually Projection of Measured Points On Surfaces as taken by Romer Arm Points Appear To Jump to Surface Fillet

5. PPL B2 Casting Romer Arm Measured Points Translated into Clamp Local Coordinate Systems x y Side B Side A SeptumBase

6. MTM B2 Casting Verisurf Points Translated into Clamp Local Coordinate Systems Note: All points lie within +/- 0.030” of Clamp Centerline x y Side B Side A SeptumBase Cells to Sort Data into for Both MTM And PPL For Averaging And Comparing

7. PPL B2 Casting Romer Arm Measured Points Translated into Clamp Local Coordinate Systems x y Side B Side A SeptumBase

12. PPL A1 Casting Romer Arm Projected Points Translated into Clamp Local Coordinate Systems x y Side B Side A SeptumBase No evidence of Points jumping To surface fillet As seen on B2
