Update Feb 7, 2003
1. Modular coil build assumptions
2. Vessel build assumptions
3. FW/internal build assumptions
4. Unknowns

VV build assumptions Vessel tolerance different on inboard and outboard Coils must slide over vessel during assembly Port stub length affects outboard, top, bottom
Tolerance zone outboard: ~ 1.875 inches
Tolerance zone inboard: ~ 1.25 inch

VV to Plasma build Gap needed for in-vessel components and scrape-off
layer (SOL) In-vessel components include trim coils, FW /divertor
panels, magnetic diagnostics, RF antennas, etc. CDR design allowed nominal space of 2.8 in (71 mm)
at trim coil location Space could be tighter away from trim coils RF antennas are special case, require more space

Unknowns What is actual assembly clearance required? What and where are RF antennas? What will be radial and lateral build of new M50 coils? Things we have not thought of

Notes:• xsec changed from 4x5 to 4.35x4.65-in• clamp space can overlap, assuming staggered clamps are ok• hard to see possible interference•healing wiggles make coil very ugly
