  1. Muon Spoiler Design/Costing Issues 5/24/2006 Jin-Young Jung, Ross Schlueter and Lewis Keller

  2. 2.25m tunnel Figure 1. Muon spoiler and tunnel

  3. Figure 2. Muon Spoiler (1.4 T in center between spoilers, 0.5-1.0 T in iron near beam pipe)

  4. Around beampipe Magnetic Field Around middle between magnets

  5. Figure 3. Muon Spoiler with vertical and horizontal trim coils

  6. Figure 4. Muon Spoiler with vertical and horizontal trim coils (zoom in) : Nulling 149 G in Bx => < 1G 5.6 G in By => < 1G

  7. Trim Coil Effect Before using trim coil After using trim coil in x, y direction

  8. Production Cost

  9. Power Consumption Small spoiler (0.64”x0.64” coil, 4x80 turns, 10cents/kWh) Large spoiler (0.64”x0.64” coil, 4x80 turns, 10cents/kWh)

  10. Highest Amp-turns without cooling For temperature rise (< 30oC): Small spoiler : 15000 Amp-turns Large spoiler : 17000 Amp-turns

  11. Installation Implications: (Spoiler mass vs. length) • Bottoms are first installed. • Then tops are installed.

  12. Implications/ Next step • Muon path, desired bend and field shape ? Possibility of Muon reflecting back to detector ? • Capital cost (7.6 milion $) vs. electrical cost (51 k $/yr) at 1.8 T. • Trim coils make less than 1 G. • For longer spoiler (18 m), going from 1.6 T to 1.8 T (10% shorter in core length) => makes 10% save in core cost ( ~ 600 k $). • Making chamfers saves 10 % of core cost ( ~ 600 k $) ? • Making top and bottom halves => ease of installation • Right and left spoilers attached together ? Or 2 cm separation ? • Space to remove and service beam pipe.
