LHCb – DT coordination Update on the Upgrade and A PT

This update provides information on the LHCb upgrade, including support for technical coordination, sub-detector integration, UT cooling, and future plans for technical support. It also discusses the UT integration TT and overall design, CO2 cooling requirements, and installation and commissioning plans.

Presentation Transcript

  1. LHCb – DT coordinationUpdate on the Upgrade and APT October 27, 2014 Burkhard Schmidt

  2. FTE by projects for 2015 Comments: • TC+Int.+Cool.: Includes support to the LHCb Technical Coordination, work on sub-detector integration, in particular for UT, and work on CO2 cooling. • For some projects the contribution will change over the years 2015-2018; this table focusses on 2015. • The Technical support for the SciFi project is insufficient from 2015 onwards. • We are grateful to DT for the help of François Garnier and Pierre-Ange Giudici to set-up the fibre quality control. • We are exploring possibilities to get technical support from the LHCb EAT after LS1 to cover a part of the need.

  3. Next steps • The tables presented here from the basis for two Workpackages (WP), clarifying the DT contribution to • the LHCb upgrade; • the LHCb operation and maintenance (update of the existing WP). • I will present a short overview at the LHCb retreat in Les Houches later on this week.

  4. UT integration

  5. TT, overall design View from the VELO downstream Distance between rails: 2760mm

  6. TT Detector box • Chain is fixed downstream, towards the magnet, where we can extend slightly – but watch the magnet coils • We only started to develop some ideas about the frame and box for UT

  7. CO2 Cooling for the LHCb upgrade Cooling requirements are being specified by VELO and UT groups

  8. Location Alcove PZ85 (VELO side) • About 25-30m2 are available and easy to access. • Area needs to be equipped with power (EXD, EBD, ESD), network, primary cooling • poor ventilation Despite some drawbacks, this seems to be the best option. • Additional advantage: • The transfer line towards VELO and UT would be rather straight. • Passing the shielding wall looks not too complicated.

  9. Installation and commissioning • An early installation and commissioning has great advantages. • See Bart’s slides in the meeting of July 8: https://indico.cern.ch/event/327053/ • An ideal period for the preparation and installation, including the transfer lines, would be the EYETS 2016/2017. • This avoids conflicts with the LHCb data taking during RUN II. • The foreseen length of EYETS 2016/2017 is 19 weeks. • All steps must be well prepared in order to use this time efficiently. • The commissioning with a dummy load could then be done during 2017/2018.
