  2. How We Intend to Assemble the Cryo-module? • Preparation of larger parts in a Clean room Class 10000 (ISO7) • Preparation of smaller parts in a “baldaquin” annex • Assembly in a clean-room Class 100 (ISO5) • Using assembly tooling specifically designed for the task • Following a predefined sequence • According to written procedures • With qualified staff • Governed by a QA plan HIE-ISOLDE Cryomodule Assembly

  3. The Assembly Tooling (Major Elements) Internal motorized frame • Consists of: • The clean room as shown by Karl • A set of rails anchored into the floor of the clean-room • Horizontal and Co-planar within 0.5 mm • An assembly frame comprising: • The fixed frame structure surveyed vertical to within ±0.5 mm anchored into the floor • An internal horizontal rectangular motorized frame that moves vertically • And that can elevate over 4m, equipment weighing up to 3 tonnes • Two rolling trollies • One multipurpose trolley MPTfor general transport of equipment • One specifically to handle the solenoid and the cavities CST • A “chevre” • hand operated • For loading equipment onto the two trollies at the Clean-room entrance door Class 100 Area Class 10000 Area Loading area Assembly Frame fixed Rails Rolling trolley (Solenoid/Cavity type) The Tooling set is designed to offer an intrinsic precision, to largely offload this burden from the assembly staff and allow them to concentrate more fully on the assembly steps in hand HIE-ISOLDE Cryomodule Assembly
