Update of Sizing of Vacuum Vessel NCSX Engineering

Update of Sizing of Vacuum Vessel NCSX Engineering Meeting February 12, 2003 Art Brooks AWB 020503 1

Overview • Improved Benchmark between Pro. E and Assemble Code – Better Treatment of Scarf Joint • Larger VV possible than shown earlier with less impact relative to CDR design AWB 020503 2

Benchmark of Codes with Scarf Joint Data at Snapshots every 10 cm Looks good so far AWB 020503 3

However, Finer Resolution Required to Confirm Assembly Code finds coil orientation at each snapshot, but does not guarantee they can be strung together AWB 020503 4

Max VV Envelope Defined by CDR VV and M 50 Assembly Path phi=0 deg AWB 020503 phi=45 deg Max Envelope phi=60 deg Tight Regions During Assembly Reduced 5

VV 16 b Vessel Provides Adequate Clearance with 6 dof Assembly reflects bounds imposed on dof AWB 020503 6

See Animation AWB 020503 7

VV 16 b encroachment on FW is minimal VV 16 b outer surface M 50 Plasma + 9. 5 cm Max Encroachment 2. 8 cm AWB 020503 8

Fitting Max Envelope still needs work Green should be everywhere outside red and inside blue AWB 020503 9

Fitting Max Envelope still needs work AWB 020503 10

Field Period Assembly Needs Fine Tuning minimal clearance ~2 cm AWB 020503 11

Summary • Improved Benchmark between Pro. E and Assemble Code – Better Treatment of Scarf Joint • Larger VV possible than shown earlier with less impact relative to CDR design • Work needed to provide better fit of Max Vessel Envelope Desirable to smooth assembly path AWB 020503 12
