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 +/ ” 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 +/ ” of Clamp Centerline x y Side B Side A SeptumBase Cells to Sort Data into for Both MTM And PPL For Averaging And Comparing
