  1. Outline • Meshed with no iron for comparison • Used Willy’s conceptual design for iron pieces • Not optimized in any way • Used thin and thick pieces • Compared fields (BMOD and BR) • Compared tracks for no iron, thick iron and “giant” iron • Reduced current density and compared optics • Note: op3 file names are: • no_iron_in_coils_test_ver2.op3 (smaller mesh size) • iron_in_coils_ver3.op3 (thin) • iron_in_coils_ver4.op3 (thick) • iron_in_coils_ver5.op3 (giant) • iron_in_coils_temp_BFIL_0_80.op3 (giant, reduced current) • iron_in_coils_temp_BFIL_0_90.op3 (giant, reduced current)

  2. No iron, coils only BMOD z=1375 cm

  3. No iron w/ mesh BMOD z=1375 cm

  4. Field on a line, middle of open sector BMOD z=1375 cm, y= 0 cm , 0 < x < -40 cm BMOD With coils only With mesh

  5. Model body in mesh

  6. Iron design thick iron thin iron

  7. Iron design 1 m long, section of tube from 0.5 to 5.5 cm radius Opening angle, thin: 5 degrees Opening angle, thick: 20 degrees Placed radially from 5 – 20 cm between 1325 and 1425 cm in z thick iron

  8. Thin Iron w/ mesh BMOD z=1375 cm

  9. Thick Iron w/ mesh BMOD z=1375 cm

  10. Giant blocks of iron BMOD z=1375 cm

  11. No iron w/ mesh BMOD z=1375 cm

  12. Thin Iron w/ mesh BMOD z=1375 cm

  13. Thick Iron w/ mesh BMOD z=1375 cm

  14. Giant blocks of iron BMOD z=1375 cm

  15. Middle of open sector With thin iron BMOD With no iron

  16. Middle of open sector With thin iron BMOD With thick iron With no iron

  17. Edge of open sector With thin iron BMOD With no iron

  18. Edge of open sector With thin iron BMOD With thick iron With no iron

  19. BMOD With no iron Z=1375, r = 16.0 cm With thick iron

  20. BMOD With “giant” iron Z=1375, r = 16.0 cm With thick iron

  21. With no iron Along straight line approximation the track of the highest energy, lowest angle particle With giant iron, BFIL 80%

  22. With no iron With thick iron

  23. With no iron With giant iron

  24. With no iron With giant iron, BFIL 90%

  25. With no iron With giant iron, BFIL 80%

  26. Summary • No optimization of the iron was done • According to this preliminary work, is 2% greater for the thick iron and about 28% greater for giant iron • Lowest tracks radial position at detector plane increased 2 cm (from90 cm) with the thick iron • Lowest tracks radial position at detector plane increased 11 cm (from 90 cm) with the giant iron (same current density) • Do NOT see a dramatic increase in the quality of the focus or size of the field • Radial focus may be a little better for transition and closed sectors • Even with giant iron pieces, only reduce field (current density) by 20% •  Not seen as a big enough gain to warrant using it
