  1. MICE: Hall Infrastructure Chris Nelson CEng CM15 8th June 2006

  2. My Profile • Recently joined project… …..But picking it up quickly! • Professional Mechanical Engineer in CCLRC Technology • 20 years experience @ RAL • Worked in all major Engineering areas; • ISIS :MARI spectrometer, experience of beamline design • Space Science :Thermal & Structural Analysis, Project management Particle physics : ATLAS Detector, Project Management, procurement of high stability CF cylindrical structure

  3. Contents • My responsibilities • Current hall tasks: Stairs/shield/platform Trench strengthening • Imminent hall tasks: Wall holes • Magnetic modelling • Fire Safety Approval • Decay Solenoid transport • Central Drawing database • Conclusions

  4. Responsibilities My MICE job • Responsible for Hall Infrastructure • Mechanical/Civil work • + Associated underlying work e.g. Magnetic analysis • Health & Safety e.g. Fire Safety Approval • Provision of Services – water, electric, ventilation • Responsible for Setting up and monitoring central drawing database at RAL • Part of Target engineering team (design & test) • Technical Board Secretary

  5. Current Hall tasks • 1) Modifying (Linac side) stairs to reduce width • Drgs out for pricing • 2) Re-Engineering (control room side) stairs/shield/platform • New set design drgs – awaiting magnetic performance confirmation

  6. Current Hall tasks • Linac side stairs –Drgs out

  7. Current Hall tasks • Shield Wall (Currently 25mm steel/100mm gap/25mm steel) Awaiting magnetic confirmation

  8. Current Hall tasks • Trench strengthening • Drgs being prepared • Non-magnetic Al used (supports + covers) near tracker along to access covers. • Decision to strengthen whole trench since layout still subject to change • About to tackle: • Wall holes for cables to MICE LCR • Wall holes for hydrogen area ventilation • Ceiling holes for emergency H2 ventilation

  9. Magnetic Modelling • New magnetic model produced • More user-friendly, Easier to quickly iterate if reqd. • Need to prove shield designs will be effective • Requirements • Shield ISIS control room • Reduce to safe personnel levels (pacemakers) • Currently making predictions

  13. Fire safety • Fire safety: Discussions started towards getting approval. • Fire exits defined, checking correct door types • Access routes being checked (minimum width, hazards)

  14. Fire safety 2 • Gap between magnets to be used as emergency access route – signs • Small/hidden areas of hall to be fenced off • Trench – blocked off with access cover and fixed steel ladder

  15. Decay Solenoid transport • Current situation: Solenoid on PSI trolley (~14.6 tonnes)

  16. Decay Solenoid transport • Solenoid assy in R55 & very unmanagable • Need to test solenoid in MICE hall • Need to work on trolley (wheels etc.) • Temporary Transport frame designed and almost ready to go out for manufacture. • Mass < 10 tonnes incl lifting frame • Can therefore be moved within MICE hall with a tandem lift (15 tonnes SWL)

  17. Decay Solenoid :Temporary transport frame

  18. Decay Solenoid:Disassembly and transport • In-situ disassembly and transport procedure • 1) Tighten centralising cold-mass supports x6 • 2) Grind off tack welds, remove end supports • 3) Lead shielding assy off nose • 4) Fit yellow cradles • 5) Fit orange beams • 6) Connect blue lifting beam • 7) Unbolt feet (keep shims) • 8) Lift onto green frame, bolt down re-using shims • 9) Refit lead shield onto nose • 10) Refit modified end supports (bolt holes) • 11) lift onto transport trailer • 12) Take to MICE Hall

  19. Drawing database • Drawing database • Initial discussions started, established some parameters • Need to maintain central database of drawings @ RAL (local to experiment) • Vital to maintain latest set of drawings (drawing control) • Need for Read access by institutes e.g. Oxford group, Imperial, etc. • Proprietary database e.g Intralink probably not suitable • I’m likely to use FTP site

  20. Conclusions • Mechanical/Civil items moving forward - Need to maintain momentum • A good scheme for disassembly/transport of decay solenoid • Early steps towards a Central drawing database
