1. 1 First wall mods status NCSX SIT Meeting Aug 12, 2002 Points at 0, 30, 60 degrees from Art Points x 1.025 and 1.00 in cross sections First try at vessel mods Dave is trying to fix winding surface

2. 2 Model RF launcher locations, typ 6 places FW panels, 360 deg shown Modular coil partial assembly Vessel with insulation

3. 3 Plan cross section 10 deg 0 deg 20 deg 30 deg 40 deg 50 deg 60 deg RF launcher locations Trim coils

4. 4 Cross section at 0 degrees  Trim coils intersect this section  Almost all points are inside first wall

5. 5 Cross section at 10, 20 degrees  Points not available yet  Trim coils intersect 10 deg section 20 deg 10 deg

6. 6 Cross section at 30 degrees  Trim coils do not intersect this section  Closest approach to first wall

7. 7 Vessel mods, try 1 First wall, as modified Original vessel modified vessel 30 deg points

8. 8 Cross section at 30 deg, with mod1 First wall, as modified Points not bloated Points bloated 2.5%

9. 9 Cross section at 40, 50 degrees  Points not available yet  RF launchers intersect these sections 40 deg 50 deg Co-ax Faraday shield

10. 10 Cross section at 60 degrees  Field joint and limiters are around this section  RF launchers on either side  Almost all points are inside first wall

11. 11 Cross section at 60 degrees

12. 12 Cross section at 60 degrees First wall, as modified Points not bloated Points bloated 2.5%

13. 13 Cross section at 60 degrees  Cross section changes abruptly  Limiter visible in this view  RF launchers on either side of this section mostly hidden by limiter limiter

14. 14 RF launcher options  Reduce number of straps to 4 instead of 6 per section  Less power?, unless strap lengths can be increased  Reduce coax to 4 inches instead of 6, maybe smaller  Move feeds farther out by running strap through “tunnels” to get straight-in shot at feed, but need more than 3 cm behind FW in these areas.  Incompatibility with inside launch and divertor operation?

15. 15 PFC panel / rib detail  Details for one concept for panel attachment developed with BFG Aerospace Plasma Vacuum vessel Heated / Cooled Rib Thermally insulated connection to vessel Panel installed Panel ass’y retracted
