1. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 1 Beam Line & Installation Plans Paul Drumm CLRC Rutherford Appleton Laboratory

2. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 2 Progressing Beam Line Layout Target Position Confirm Beam Angle Locate Position of hole Locate Line for MICE(almost)

3. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 3

4. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 4 Target Development active system sharp dip into beam just prior to extraction use fact that beam vanishes for ~10 ms –Reduces strain on drive mechanism low mass design – recoil-less

5. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 5 active target design University of Sheffield (Booth) RAL – ED (Bradshaw) Interface to ISIS (ISIS)  reliability  reproducibility

6. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 6 Beam Optics – Optimisation ? Beam Out of Solenoid – Large Emittance Looking at options of –quads before 2 nd dipole –quad after 2 nd dipole –ideally - focus beam ~ mid way between TOF detectors

7. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 7

8. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 8 IPRC on the beam line …is it sufficient to make the hole in the shield wall in the next long shutdown? …when would the beam line be completed? …would this preclude the use of the PSI solenoid? …subsequent delay in the mice programme?

9. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 9..questions …impact on the funding & resource profile? …timescale for decision on the use of the PSI solenoid?

10. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 10 ….local factors –UK Financial Position – scrape by in 03/04 –ISIS shutdown: – installation of RFQ –ISIS management advice: look at a "minimum" plan for ‘04 Shutdown

11. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 11 Future Shutdowns Possible Shutdowns? …hypothetical picture

12. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 12 Use 04 shutdown to cut hole? Consequence  beam line not finished until early 2006 –PSI Solenoid - known quantity early in 2004 –No intermediate beam line envisaged  lose opportunity to –characterise beam –test first solenoid+tracker –test other detectors

13. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 13 Delay ? 6 months late to start with MS4 Sequence of Measurements maintained  1 year late with full MICE ?

14. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 14 ….interactions when will solenoid + tracker be ready? when will absorber & focus coils be ready? When will cryogenics system be ready?

15. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 15

16. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 16 The fact that ISIS will have subsequent shutdowns had been ignored…. Cost of ~3 months per year ….hypothetical picture

17. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 17 What RAL will do now….. clear hall during 2003/4 cut into synchrotron during 2004 shutdown start working on target progress design & installation plans …. to enable full funding from pparc/clrc when the risks (for pparc) are clearer.

18. march 2003 Paul Drumm MICE Collaboration Meeting, CERN 18 What RAL Needs from MICE…. For Installation Planning –Demarcation of responsibilities (formal) installation running decommissioning & removal –how are the MICE timescales evolving? realistic time scales planning of installation & experiment
