  1. Steve Virostek for Allan DeMello Lawrence Berkeley National Laboratory MICE Coupling Coil Update MICO January 23, 2013

  2. Current Status of Coupling Coil • Cold Mass • By-pass of cooling pipe leak installed • Pressure test of all cooling pipes complete • Vacuum check of all cooling pipes complete • Shipping to Fermilab today • Cryostat • Drawings are complete • LBNL mechanical shop will fabricate the first cryostat • Purchase order for stainless steel placed

  3. By-pass pipe Section view Helium reservoir Pipe capped • Location of leak • Section of pipe cut out By-pass pipe • By-pass pipe • Original pipe

  4. By-pass pipe • Location of leak • Section of pipe cut out • By-pass pipe • Fermilab • magnet test • fitting • Original pipe • Fitting location for Fermilab magnet test is same as the original pipe

  5. By-pass Cooling Pipe Pressure Test • The by-pass cooling pipe was hydrostatically tested, in steps, to a pressure of 300 psi • No leaks detected • Vacuum tight

  6. Pressure Test of Other Cooling Pipes • Other two cooling pipes were hydrostatically tested, in steps, to a pressure of 223 psi • No leaks detected • Vacuum tight Upper cooling pipe being tested Lower cooling pipe being tested

  7. Coupling Coil Cold Mass Ready to Ship Coupling coil cold mass in crate Coupling coil cold mass wrapped for shipping Coupling coil cold mass moved to crate

  8. Coupling Coil Cryostat Single Cavity Vacuum Vessel Exploded View

  9. Coupling Coil Cryostat • Cryostat design is complete • Drawings complete • LBNL mechanical shop will fabricate the first cryostat • Purchase order for stainless steel placed • Estimated to take 6 months to complete fabrication • Drawings will be updated to reflect the “as built” cryostat
