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)
