1. H.TauregTB December 20041 B-Field Mapping

2. H.TauregTB December 20042 Schedule Install equipment: May 2005 Start mapping: mid June 2005 Finish mapping: August 2005, latest

3. H.TauregTB December 20043 Mapping programme L3 and dipole at two polarities –Only ++ and -- combination L3 at 0.2 and 0.5 Tesla –Dipole powered always at same level L3 alone –At 0.2 and 0.5 Tesla and both polarities In L3 –Space Frame volume –EMC, HMPID, PHOS volume

4. H.TauregTB December 20044 Grid size Dipole –80 mm in x, y, z L3 –100 mm in r and z –2° in φ for r > 2 m –4° in φ for r < 2 m

5. H.TauregTB December 20045 Grid size Fine grid as above Coarse grid –Increase step size by factor 3 In φ and z for L3 In z for dipole

6. H.TauregTB December 20046 Mapping scheme

7. H.TauregTB December 20047 Mapping work Continuous, 24 h / 24 h Team of at least 3 Set up changes during normal working hours Time estimate to be worked out

8. H.TauregTB December 20048 Hardware Support structure to be adapted for dipole Support structure to be adapted for L3 Measuring arms to be constructed for L3
