1. Mechanics: 2013-2016 (Tim)

2. General Proposal • Programme • Strip Module Assembly & QA (WP2) • Strip Stave Assembly & QA (WP4) • Assembly, Integration & Internal Services Design (WP4) • Strip & Pixel Test & Systems Support (WP3) • Should show completion of R&D/Prototyping and have a clear transition to production readiness. • Main change (WP4) is to create a dedicated “Integration” work-package • Integration means Design, services, stave insertion, etc • Pointer towards involvement at CERN for final assembly & test of barrel tracker

3. 3: Strip Stave Assembly & QA Specification and final design of all components which required to build staves cores and attach modules. Development of stave core assembly and module mounting tooling, stave life-cycle handling frames and electrical and thermo-mechanical QA systems. The assumption is that there will be two stave assembly clusters, however reception testing / manufacture of components (eg. Tapes, EOS cards, cooling circuits, etc) might be distributed. • Tapes Development of 130nm tapes as required. Production and procurement. Testing. Provision of tapes for prototype work. SP and DC-DC. Short staves and full size. • EoS and Optical Interface EoS ‘card’ development, integration onto stave, including GBT for both strips and pixels. • Core Assembly Skin, close-out and ‘honeycomb’ or equivalent manufacture. Prototype development for lowest mass. Assembly of core including co-curing, cooling and EoS attachment. Assembly includes mounting components and alignment system parts; Supply of stave cores to the development programme. • Module Mounting Development of equipment and procedures for attaching and removing modules to and from staves. • Testing and Shipping Design of life-cycle shipping and test system. Procurement and provision of components for these needed as part of the programme. • Production Preparation Preparation for serial production of above items, including manufacture of multiple tool sets and formal specification of procedures, division of work, QA and organisation. • Strip Electrical and Mechanical QA Development of appropriate handling and QA procedures for handling and storage of raw materials (pre-preg, glue, ), assembly sequences (curing, annealing) and test procedures associated with ensuring assembled products meet specification..

4. 4: Assembly, Integration & Internal Services Design Development and demonstration of the techniques needed during assembly of staves to the macro support structures. Design and feasibility demonstration of the end-of barrel region and the service module. Includes tooling and preparation for build. • Barrel Assembly Sequence / feasibility Development of assembly sequence including welding, end insertion. Includes development and a mock-up of end insertion. • Barrel End Region layout Design Design of pipe layout ,interlinks, cable routing, fibre paths, connector locations. • Pixel Disc Services and Integration Design Definition and design of interface to global mechanics. Layout of services to PPX • Strip Service Module Design/mock-up Design and mock up of the service module • Strip Assembly Tooling Tooling associated with assembly of the service modules, end-insertion, connection of service module to the barrel. • Assembly Production Preparation Preparation for serial production of above items, including manufacture of multiple tool sets and formal specification of procedures, division of work, QA and organisation. • Strip Cooling Pipe definition; qualification; bending; jointing including welding methods; connectors tests. Provision of parts for prototype work. Titanium and Stainless pipes. Provision of any plant needed. • Strip Alignment Conceptual design and layout of weak-mode alignment system. Prototype design, fabrication, procurement and test.
