Preparing TPC Installation TB 14.9.06 Peter Glässel, Heidelberg
Preparations in SXL2 • Remove clean room wall (towards Muon area) and roof • Clear area for trailer • Setup hydraulic station DF + TPC DF + TPC TB 14.9.06 Peter Glässel, Heidelberg
Hydraulic station • Alternative: mobile crane plan view side view TB 14.9.06 Peter Glässel, Heidelberg
Complete TPC/TRD heat screen Platform under shaft: intermediate support for Delphi Frame (DF) Before L3 magnet Support for DF (surveyed) Space Frame area I-bars stored at BF Connection rails at BSF ITS platform (used when moving TPC) Preparations in UX2 TB 14.9.06 Peter Glässel, Heidelberg

Special precautions • DF has 4 feet, but no deformation allowed • Lifting jig is 3-point • 4-point floating hydraulic support • 3-point support (on trailer) • TPC is a closed volume, safety bubbler with Δp < 1 mbar • Watch Δp, ΔT to avoid sucking air • CO2 bottle on DF for replenishing TB 14.9.06 Peter Glässel, Heidelberg
TPC transport • Transport document is prepared • DF + TPC: 24 t • On SX2 crane from clean room to hydraulic station • Raise to allow trailer to pass under DF • Lower onto trailer • Transport on trailer to SX2 • Pick-up with hydraulic station • Lower to allow transfer to SX2 crane • Lower into shaft onto intermediate support • Transfer to UX2 crane • Move to final support before L3 magnet TB 14.9.06 Peter Glässel, Heidelberg

ITS platform • Any number of segments possible TB 14.9.06 Peter Glässel, Heidelberg
Installation sequence • Based on previous experience in TPC-ITS integration test • Align, install connection rails • Move to IP under survey • No adjustments of SF during moving foreseen, expected deformations < 2mm (cf. tolerance for beam pipe ±5 mm) • Align TPC at IP • Move back to ‘parking position’ under survey • ITS installation TB 14.9.06 Peter Glässel, Heidelberg

Alignment of TPC with Beam Axis Once the TPC is in the final position, the TPC axis is aligned with the beam axis. Again, only the x,y,z, coordinates of the outer (and possibly inner) reference rods on the shaft side can be used to determine the position of the TPC. TB 14.9.06 Peter Glässel, Heidelberg
Installation of 1st ITS rail section Two 6m sections of the ITS rails are inserted through the TPC and fixed by the ITS rail fixation points on the frontabsorber. Then, the fixations points are slightly opened to allow the ITS rails to move to the parking position together with the TPC. Since we assume that after movement of TPC to parking position and back to the IP the TPC ends up in the same position, the above procedure will make sure that the ITS rails are well aligned with the TPC when it moves to the IP.
