Current Base concept (all sites)

Udo Wagner

  • The 17 K limit for the MgB2 link allows only the 5 K, 3.5 bar helium from line C as coolant.

  • The link will be cooled by helium gas created by evaporating the liquid helium in the spice box.

  • Thermal shield solution not shown.

    • Either with 20 K, or with 70 K gas.

Helium at max. 17 K

Helium from line C

Minimum change approach

Minimum change approach

WP6 Meeting

  • Minimise work in the tunnel

    • Assemble and test before LS2 starts

    • Aim for installation within short time slot (radiation cooldown time may be long..)

  • Remove HCM only and replace with DFA

    • Keep 2x13 kA leads in current position

    • Keep cryo jumper in current position

    • Vertical link connection

    • Keep existing support beam and shuffling module

  • Remove DFBMH and link Q6 to DFA

    • Possibly with no changes to Q6 QQS and jumper

    • Link routed above QRL

DFA to Q6 in NbTi

Supercritical He because of changes in level

52x600 A

4x600 A

Keep jumper and 13 kA leads in same location to avoid changes in power cables and cryo distribution

Splice

Typical time scale

Typical time scale

WP6 Meeting

  • From an established concept to ready for tendering documentation: 1 year (usually more...)

  • Tendering: 6 months

  • Fabrication: 1 year

  • Ready for installation: + 6 months (possibly more if cold tested)

  • i.e. 3 years minimum

  • We should start now:

    • Agree on the cooling scheme

    • Validate integration in the tunnel (links and DFA)

    • Determine piping dimensions and extent of modifications to QRL and Q6

    • Start the DFA and Q6 link mechanical design
