Overview

• The issues
• The areas presented
• Open issues
• What we have aimed to show
• Our objectives

3
The issues

• Formal brief
• 1. endorse the main mechanics of the EE,
• 2. endorse the proposals for Dee assembly and the
  installation scheme,
• 3. endorse the definition of the services and
  cooling pipes external to EE taking into account
  the evolution of the VFE electronics.
• Related areas
• Is the design of the major mechanical components
  sound?
• If we freeze the design of the major mechanics
  now, what are the implications for further work
  on the electronics?
• Why do we need to start manufacture of the large
  components now?

4
The areas presented

• Major mechanics
• Structural and thermal analysis
• Tests
• Assembly of Dees
• Services
• Integration
• QA issues
• Timescales
• Formal response to EDR-04

5
Open issues

• Cooling pipe type (extrusion/braze, etc)
• Choice will be influenced by capabilities of
  selected supplier
• Precise locations of support holes for components
  behind backplate
• Choice is rather constrained by geometry,
  interacts with mechatronics
• Exact location of patch panel fixing holes
• Could be added after manufacture
• Finalisation of material for ring flange and
  backplate
• May be negotiated with supplier for best price
• Location of tapped holes in Positional spacers to
  mount to manipulator
• Must be fixed before m/f, studies on manipulator
  in hand
• SE interfaces spider fixing hole details and
  services fixings
• Discussions in hand with Piet Wertelaers

6
We have aimed to show

• That the mechanical design is sound and fully
  supported by relevant calculations
• That the assembly and integration schemes are
  feasible
• That the services are manageable and the other
  interfaces are well defined and respected
• That we must freeze the design now and proceed to
  tender in order to meet the CMS timescales
• That to freeze the design of the major mechanics
  will not have a major impact on the work
  currently in hand to design the mechatronics

7
Our objectives

• We seek from the reviewers
• Endorsement of the points made on the previous
  slide
• Commentary upon the design and any suggestions
