1. Interconnections Cryogenic Extensions and DSL Ivo Slits - AT/MCS 08.11.2006

2. Ivo Slits, AT/MCS-IC, 08.11.20062 Introduction A cryogenic extension allows to link the QRL jumpers to different clients (DFBA, DFBL, Q6, ACS). The diameter of the cryogenic extensions is 355.6 mm QRLXD-Q6 - 8R - QRLXE-DFBLA - 1L - QRLXH-Cavité - 4L - Q6 Jumper QRL DFBL Cavité Jumper QRL

3. Ivo Slits, AT/MCS-IC, 08.11.20063 Introduction They are composed of several interconnection pipes (between 4 and 9 pipes) with different internal diameters (from 10 mm to 80 mm) Interface of the cryogenic extension element QRLXD (sector 8-1) Interface of the cryogenic extension element QRLXE (sector 8-1)

17. Ivo Slits, AT/MCS-IC, 08.11.200617 Activities AT-MCS Interconnection drawings (support TS-MME); Procurement of interconnection components (sleeves, flanges, MLI, electrical insulation) except for plug (supply AT-ACR); Procurement tooling; Realisation of DSL interconnections with magnets/DFBs in the tunnel.

19. Ivo Slits, AT/MCS-IC, 08.11.200619 1)Interference with supports of vacuum chambers -> AT-VAC will do modifications 2)Support for DSL- flexible that will be fixed to the support of the vacuum chambers (AT-MCS) or individual support. 3)VAB supports are adapted to pass the DSL-flexible 4)Interference between DSL flexible and support BPTX at 5R. AB-BI will do the modification. Note: The interconnection DSL/magnet shall be done before the installation of VAB supports and vacuum chambers in the adjacent zone. Integration
