Preparing TPC Installation

TB 14.9.06 Peter Glässel, Heidelberg


Preparations in sxl2

Preparations in SXL2

  • Remove clean room wall (towards Muon area) and roof

  • Clear area for trailer

  • Setup hydraulic station

DF +

TPC

Preparations in ux2

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

Special precautions

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

Tpc transport

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

Its platform

ITS platform

  • Any number of segments possible

TB 14.9.06 Peter Glässel, Heidelberg


Installation sequence

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

Preparing tpc installation

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.

Preparing tpc installation

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.
