Introduction to IBL project IBL : Insertable B-layer B Like “Beauty” An additional layer of Pixel will be inserted into the Pixel detector of ATLAS Why an additional layer ? To be closer to interaction point and closer to the decay of the Beauty particle To gain into track reconstruction by having a 4th point To compensate the ineluctable degradation of the current B-Layer To implement the most recent silicon and chips technology 14/05/2012 R.Vuillermet

Scenario and tooling for beam pipe extraction and IBL insertion The removing the beam pipe in situ, is an operation that was never imagined during the design of the Pixel supporting structure. This operation is delicate for several reasons : The beam pipe is a long object (7.4m) The beam pipe deforms under its own weight of about 40mm, when place on 2 supports at its extremities The pixel modules are radially located at 8 mm from the beam pipe and are extremely fragile The wire system that support the beam pipe is not directly accessible as it is located at 3m from any hands access The working space to insert tools are rather small The possibility to control visually the removing operation is limited or impossible ... Despite what is looking like “impossible mission” we have imagined tools and procedures to perform this extraction operation And have developed a scale one mock-up of the inner detector and its environment to test, improve, practise the tools and procedures 15/11/2011 R. Vuillermet

Remove the beam pipe Concept and tools PP1 support Beam pipe support : A-side C-side Central wire support Concept : As their is not space out of the beam pipe to access and support it we have explored what can be done from the inside the beam pipe The tools The Long Guiding Tube (LGT) The LGT was imagined and design such that it can take the load of the beam pipe and can control actively its central deflection (using muon alignment system connected to a tension mechanism). Once on the LGT, the beam pipe can slide out of the inner detector. The collar removing tools The collar removing tool is disassembling the collar and collecting the wires such that the beam pipe can slide through the Pixel B-Layer. Reception tooling For support, and handling of the different items that need to be transfer with the surface. 15/11/2011 R. Vuillermet

Remove the beam pipe Concept and tools The beam pipe flange on A-side is too close to the B-layer envelope . The flange need to be cut on the aluminum section The LGT is inserted inside the Beam Pipe and supported at both sides. The support collar at PP0 A and C-side are disassembled and extracted with wires at PP1. Beam pipe is extracted from the C-side and it pulls the wire at PP1 New cable supports are inserted inside Pixel volume at PP0. A support carbon tube (Inner Support Tube IST) is pushed inside the Pixel volume along the LGT. C-side A-side 15/11/2011 R. Vuillermet

The LGT with a space frame are moved out from the IST The IST is supported in 2 points at PP0 by the wire system and on PP1 walls on side C and A at the level of the Pixel cruciform. The LGT with a space frame are moved out from the IST . The new beam pipe with the IBL Package are inserted from C-side. C-side A-side 15/11/2011 R. Vuillermet
