1. Agreement on scope of supply and extent of interface among different suppliers of the AFC module This talk covers the scope of supply on the Absorber Focus Coil Module between Oxford/RAL, KEK and NIU/IIT. AFC Engineering Group meeting on 26 th January 2004 by Wing Lau, Oxford

2. NIU / IIT will supply the following:- The Absorber windows, the Safety windows; the Large end plates. It should provide the following interface information to:- the Absorber Body supplier:- Absorber Window and flange dimension Others? the Focus Coil Module supplier:- PCD, size and number of the threaded holes for the Safety Window and the Large End Flange Surface finish at the seated area of the mechanical seal Others? Should the Window supplier require any design information from both the Absorber and the Focus Coil Module suppliers, such request should be made before the end of February 2004 to allow the re-baseline drawings to be completed before the MICE Collaboration meeting at CERN at the end of March 2004

3. KEK will supply the follow:- Absorber Body; Liquid Hydrogen and Gas Helium feed pipes to and out of the Absorber body to the Focus Coil Vacuum Vessel inlet entrance nozzle; Anchoring arrangement for the Absorber body; LH2 Spillage bucket; As a minimum, it should provide the following information to:- The Window supplier:- PCD, size and number of holes for the Absorber Window attachment Surface finish at the seat area of the mechanical seal; Mechanical seal and bolting requirement to guarantee leak-tightness; Window flange geometry required to allow the routing and attachment of the LH2 and GHe feed pipes; Others? The Focus Coil supplier:- Anchoring details for Absorber body and the LH2 spillage bucket; Any fixing arrangement for the LH2 and GHe feed pipes; Sealing arrangement between the feed inlet pipes and the entrance nozzle to the top of the Warm Vessel. Others? Should the Absorber supplier require any design information from both the Window and the Focus Coil Module suppliers, such request should be made before the end of February 2004 to allow the re-baseline drawings to be completed before the MICE Collaboration meeting at CERN at the end of March 2004

4. Oxford / RAL will supply the follow:- The Focus Coil Modules except those in the KEK and NIU/IIT’s scope of supply; Support structure for the Focus Coil Modules As a minimum, it should provide the following information to:- The Window supplier:- Space envelope and dimension of the Focus Coil Warm bore tube and its Safety Window attachment ring; Space envelop and dimension of the Large End Flange attachment ring; Others? The Absorber supplier:- Space envelope and dimension of the Focus Coil Warm bore tube; Space envelope and dimension of the Large End Flange attachment ring; Space envelop for the LH2 & GHe feed pipes between the Large End Flange and the Cryostat; Size and location of the Warm Vessel top entrance nozzle; Space envelop for the LH2 spillage bucket; Any fixing constraint for the LH2 and GHe feed pipes; Others? The Coupling Coil and Detector Module suppliers Solution on the connection between modules Common agreement on the structural support design for the modules Others Should the Absorber supplier require any design information from the other suppliers, such request should be made before the end of February 2004 to allow the re-baseline drawings to be completed before the MICE Collaboration meeting at CERN at the end of March 2004

5. Drawing showing the scope of supply on each of the 3 package supplies on the Focus Coil Module is on the next page. As for the Instrumentation and monitor control, this will need to fit into the existing space envelop and any additional space requirement should be negotiated with the package suppliers as and when needed.

6. Definition of supply scope between Oxford/RAL, NIU/IIT and KEK Colour code:- Oxford / RAL supply is in black; KEK supply is in blue; NIU / IIT supply is in red Pink indicates interface areas

8. Interface Colour Codes With Focus Coil Module supplier, i.e. Oxford / RAL With Absorber supplier, i.e. KEK With Window supplier, i.e. NIU / IIT With Coupling Coil and / or Detector module suppliers Parts marked in Pink colour are interface parts
