Engineering design

• Straight and elbow pipes are in Invar material• The extremities of each interconnection pipes are

equipped with Stainless Steel sleeves• Most of cryogenic extensions have no active thermal

shield. Each interconnection pipe is equipped with MLI. Only cryogenic extensions QRLXF and QRLXH (linking ACS) have active thermal shield.

• The vacuum jacket is in Stainless Steel.• The number of elements composing one cryogenic

extension can vary from 1 to 4 elements.• Interconnection pipes are supported inside the vacuum

jacket with spacers• The thermal losses per meter is around equal to ~ 1.5

W/m.• External interconnections are made with rigid sleeves.• Horizontal cardan compensator on QQS jumper side.• Flexible hoses are added on Q6 and DFBA side for the

cryogenic extensions QRLXD, QRLXA, QRLXC, QRLXK and QRLXL.

Fabrication

• Main issues» The fabrication takes place at DTA (Air Liquide-

Sassenage).» Each interconnection pipe (Invar) is He tested after the

prefabrication.» The possible weld interfaces can be :

• Stainless Steel / Invar• Invar / Invar

» Each weld is X-rayed (norm EN 25817-Class B) and have associated qualifications

» Each cryogenic extension undergoes the following tests :

• Pressure test• He test• Cold test
