1. 8/07/2002 - J.M. Rey1 J.M. Rey CEA/DSM/DAPNIA/SACM Saclay The different (magnetic) ways to run the MICE experiment

2. 8/07/2002 - J.M. Rey2 Magnetic configurations 3 ways to run the experiement: Cold: 1 absorber, 2 detectors. Flip: 2 absorbers, 2 flip region, 1coupling, 2 detectors. Straight: 2 absorbers, no flip region, 1coupling, 2 detectors Is that enough!

3. 8/07/2002 - J.M. Rey3 Cold Cold: 1 absorber, 2 detectors.

4. 8/07/2002 - J.M. Rey4 Flip Flip: 2 absorbers, 2 flip region, 1coupling, 2 detectors.

5. 8/07/2002 - J.M. Rey5 Straight Straight: 2 absorbers, no flip region, 1coupling, 2 detectors

6. 8/07/2002 - J.M. Rey6 The detector point of view On axis field contribution of the experiment in the detector: 0.1% for a 5T field

7. 8/07/2002 - J.M. Rey7 The detector point of view The adjustement of the field homogeneity in the detectors will require specific compensating coils. It seems reasonable to consider one set of compensating coils per experiment configuration. This kind of device may have a significant impact on the costs, especially if they are not mentioned on the specifications!

8. 8/07/2002 - J.M. Rey8 Some questions? What is the lowest magnetic field, or muon momentum, to be measured in the detector magnets? Should the 10 -3 field homogeneity be kept even for the lowest field? Are they some more experiment configuration? Should we fear the next slide?

9. 8/07/2002 - J.M. Rey9 Some fear? -10% +10% -10%

10. 8/07/2002 - J.M. Rey10 Toward magnet specifications! We have defined: The inner warm radius: 20 cm. The good field length and radius: 1.1 m and 15 cm. The maximum field: 5T. We need to define: The minimum field. All the foreseen experiment configuration. The range of adjustment for the different coils.
