Pixel Mechanics Meeting

April 26-28, 2001

LBNL

Here is the proposed rough agenda for the pixel mechanics and services
meeting to be held at LBNL on April 26 - 28, 2001. Logistical
information(room location etc will appear in a different message).

The primary purpose of this meeting is to prepare for the overall pixel
mechanics Conceptual Design Review and the local support Production
Readiness Review that will occur at CERN on June 18-19, 2001. A proposed
draft agenda for the CER/PRR is given at the end of this message. Thus
our meeting on April 26-28 is intended to be a detailed working session,
keeping presentations to a minimum. In addition to the usual overhead
projector, we plan to have a computer-driven projector for your laptops
so that models/drawings may be shown as required. Network access will
also be available in the meeting room. If you cannot bring your
models/drawings via laptop or have them viewable via network, please
bring prints or whatever else is required.

Rough agenda and major topics follow.

April 26

AM Services design, prototypes and interfaces

Flex-\> Pigtail(s)/Type 0-\>PP0-\>PP1. Most(if not all) of the principal
design members will be at the meeting. Focus on outstanding issues that
must be resolved before June.

Resolve interface issues to staves and sectors and update local support
interface document. This includes grounding, shielding.

Interfaces to barrel shells, cone and disk rings.

Interfaces to support frame.

PM Cooling connections, design and interfaces

Summary of ongoing work on coolant connections.

Preliminary(final?) definition of coolant connection for stave and disk
for PRR.

Baseline choices up to PP1? Is this possible?

Work program to continue design and prototype validation.

Supplementary cooling. Are additional cooling circuits(not connected to
local supports) needed for cooling services within support tube?

April 27

AM Local supports

Drafts of all documentation needed for the PRR of staves and sector
should be available already by the April meeting. Preliminary
construction schedules also.

Review of drafts. What issues(must be few) remain to be resolved?

PM Global supports

Brief summary of shell, ring and support frame design and prototype
status.

Interface issues(may also continue discussion of services interfaces, if
needed)

Layer 1/2 Shells \<-\> Cone

B-layer \<-\> Cone

Rings \<-\> Frame

Frame \<-\> Support Tube

April 28

AM Support Tube, Services Support and Installation

Installation scenario and impact on structural design,
services(particularly breaks)

Related to this is the installation checkout scenario(electrical and
coolant connection testing during installation process)

Status of support tube design, mockup, prototype plans, including
service support panels

PM Open

Previous sessions likely to run late so this is for spill over

Also with the exception of some work done more than one year ago, the
final ASSEMBLY/TESTING scenario on the surface at CERN has never been
discussed in any detail. What can we do in the time available to fill in
this hole before June?

Discussion of CDR/PRR agenda.

Very preliminary agenda for June CDR/PRR(and suggested speakers)
