Overall planning

Conceptual design, studies on materials, technologies

, cooling

D. Abbaneo

First major milestone: TP in autumn 2014Describe a mechanics concept (consistent with the proposed detector layout!), with detector modules, support and cooling structures, services arrangements. Also initial plans on how the detector can be constructed, assembled, tested and commissioned.

Collaboration between design teams, meetings

Until the upgrade project has chosen between the proposed, different Tracker layout concepts, the mechanics design work needs to continue on all of them.

Mechanics design teams should collaborate to:1. Identify and share common topics (e.g. choice of adhesives, cooling pipe material and connection

techniques)2. Allow for cross-checks between designs3. Avoid duplication of work4. Avoid leaving topics completely or poorly covered.

Collaboration between the design teams:1. Use Web-accessible data storages

Common ones: https://espace.cern.ch/Tracker-Upgrade/SitePages/Home.aspx and EDMS (both need a brush-up!)+ Storages maintained by each design team

2. Hold Phase 2 Mechanics meetings every ~2 months. See next slide for 2013 CMS calendar.

3. Hold a Review on the Phase 2 Mechanics in summer-autumn 2013.4. And of course email and phone.

N.B. During CMS Weeks difficult to

find time for Upgrade meetings
