4. Cavity Packages 2009/8/25 19th Biweekly Webex meeting (S1-G, Cryomodule, Cryogenics) 4 From the KEK modeling Gate valve 1385.6 at room temperature A B A: The present shield design by FNAL/Don has an interference with the gate valve. The length of the shield in the solid model by Don is 351.5 mm while the length might be 286.5mm. B: The length of the FNAL shield is 351.5 mm. For overlapping to DESY shield, the length might be 231.5 mm. The length between the input couplers is 1385.6 mm at room temperature. In the drawing by Don, the distance is 1385.15mm. Are the modeling made at cold temperature?

5. Input couplers 2009/8/25 19th Biweekly Webex meeting (S1-G, Cryomodule, Cryogenics) 5 By Don The enclosed components by white circles are required for assembling and supporting warm coupler and vacuum pipes. The hole on the shield has interference with the coupler components.

In some components, the seals and bolts are missed. – FNAL cavities in KEK modeling are based on the CAD data by Don. 2009/8/25 19th Biweekly Webex meeting (S1-G, Cryomodule, Cryogenics) 6
