Summary: PPPL metrology of VVSA1 match the data pattern provided by MTM and the offset value is in the same range as the data points provided by MTM.
435 points are shown with .1875” + an additional .050” offset above nominal position.
MTM data
497 points are shown with .1875” + an additional .050” offset above nominal position.
PPPL data
Data on far side of VV (see next slide)
All points are on the vessel outside surface
All points are on the vessel outside surface
497 points are shown with .1875” + an additional .050” offset above nominal position.
PPPL data
435 points are shown with .1875” + an additional .050” offset above nominal position.
MTM data
Overlay of PPPL and MTM data (all outside shell surface points).
0.396” yellow offset
0.543” blue offset
0.421” yellow offset
PPPL - yellow spheres
MTM - blue and light green spheres
0.430” blue offset
PPPL - yellow spheres
MTM - blue and light green spheres
426 points are shown with .1875” + an additional .050” offset below nominal position.
MTM data
361 points are shown with .1875” + an additional .050” offset below nominal position.
PPPL data
All points are on the vessel inside surface
Although the points are different the size of the offset is about the same (see next few slides)
