1. Step IV Infrastructure update STFC Tim Hayler Eddie Holtom Norbert Collomb Graham Stokes 14 th December 2011 MICO170 meeting 1Tim Hayler

2. MICE major Infrastructure milestones TaskBaselineStatus Downstream spectrometer solenoid base plate installation complete 31/12/11Complete He window manufacture complete 30/6/12Detail drawings complete, currently out for Quotation. TOF cage and Virostek plate bracket design complete 31/12/11Detail drawings complete, currently out for Quotation AFC rolling platforms tested31/12/11Complete Radiation shield manufacture and testing complete 30/3/12Design review held at the Technical board meeting 21 st November, some open issues. Ready for AFC & SS installation 30/3/12Depends on the MICE hall schedule of events 2Tim Hayler

3. Downstream spectrometer solenoid base plate installation complete All step IV base plates installed: Upstream spectrometer base plate (in beam and out of beam) AFC base plate (in beam and out of beam) Downstream spectrometer base plate (in beam only, there will be no possibility of moving the downstream spectrometer out of beam) 3Tim Hayler

4. He window manufacture, currently out for quotation 4Tim Hayler

5. TOF cage and Virostek plate bracket design complete Detail drawings of the bracket design are complete. We have worked closely with the Spectrometer team to make sure all the necessary compliance is in the design e.g. The way the brackets fasten to the Spectrometer and positioning of the TOF cage. Currently going through the tendering process. Expect delivery in march 2012 5Tim Hayler

6. TOF cage and Virostek plate test support stand Support frame to test: The bracket assembly to the TOF cage and Virostek plate. TOF detector assembly, movement of the detector on the sliding mechanism. The mechanical arm for removing the split ring Expect the need to do some re-work on the Virostek plates, split rings, drill and tap holes, some machining Expect to start the build in March 2012 6Tim Hayler

7. AFC rolling platform tests complete Testing specification for the MICE Moving Platform: Ensure the platform raises and lowers and moves horizontally Leak check/pressure drop check (Hydraulic system) Ensure the platform raises sufficiently to permit moving the unit without interference Visual inspection of components under load regarding deformation There are no unforeseen failures of components The moving of the platform along its intended path 7Tim Hayler

8. AFC rolling platform tests complete 4 tonne load test done at Daresbury Lab Hydraulic jacks raise the platform. Roller stakes move the platform in and out of the beam. 8Tim Hayler Final testing needs to be done in the MICE hall early 2012

9. The Radiation Shield The review presentation is on the technical board website, meeting minutes 21 st November 2011. http://mice.iit.edu/tb/Meetings/2011-11-21/http://mice.iit.edu/tb/Meetings/2011-11-21/ 9Tim Hayler

10. Actions from the radiation shield review ActionDateResponsibleStatus A test plan devised for all operating scenarios (in vacuum) 02/Jan/2012Norbert Collomb WIP Manual method to open and close the shutter doors 02/Jan/2012Norbert Collomb WIP Add radiation monitor to the design 01/Feb/2012Tim Hayler and Norbert Collomb Need specification from the collaboration 10Tim Hayler

11. Spectrometer Solenoid stand Tim Hayler11 Support frame design is being worked on at RAL with close collaboration with the Spectrometer team

12. Spectrometer Solenoid stand Tim Hayler12 The frame will be built in the UK and installed in the MICE hall as part of the Step IV build The Spectrometer team will now provide the SS with just the four support feet shown. This helps with shipping issues.

13. Local magnetic shielding for the MICE hall compressors and beyond Tim Hayler13 Prototype being made in mild steel for a fit check

14. Ready for AFC and SS installation 30/03/2011 The readiness date for the AFC and SS installation is very much dependant on the MICE hall schedule of events. We want to install all the moving platforms for step IV Can we move the KL detector downstream to progress the Engineering build in the first SS position? First raised at the TB, 21 st Nov meeting, slides by Ken Long http://mice.iit.edu/tb/Meetings/2011-11-21/ http://mice.iit.edu/tb/Meetings/2011-11-21/ Are we taking beam in the first quarter of 2012? What is the Hydrogen project doing? What other work is scheduled for the first quarter 2012? In building up the Infrastructure we would expect unknowns, items lost and unforeseen events. It would be very useful to start the work in January. Tim Hayler14
