4) Goal of the meeting:
CDR Review Guidelines Version 2 - 98November09 P. J. Napier
Select a baseline
design to continue with detailed implementation work ...
The purpose of the CDR of an MMA Subsystem is principally
to review 3
(1) Are the detailed requirements for the subsystem complete and
(2) Will the design selected for implementation on the test array
(3) Are interfaces to other subsystems defined adequately and completely?
(4) Has adequate attention been given to the produceability and
of the subsystem?
Meeting organization and attendance to be the same as a PDR. MMA199901-0010
I think that we should leave this meeting with one design and one philosophy
to guide iterative changes. This design will then be passed to engineers.
When we understand contraints imposed by the site construction plan and
iterate those into the design, the ALMA Configuration Design will be complete.
From the latter report:
GOALS & DELIVERABLES
The ALMA configuration design should include
- location of the pads
- the length of roads, using a maximum
15 % grade to the road layout
- a tentative layout of the conduits, which
should limit the number of road crossings
- the location of the ACA (the design of
the ACA configuration is a separate package)
- a suggested location of the buildings
- considering the current ALMA planning,
the deadline is September 1st, 2001.
Task division should be agreed upon with
the ALMA management ASAP. Considering the work done up to now, three groups
appear in a position to provide a design: NRAO (L.Kogan), OSO (J.Conway)
and DEMIRM (F.Boone & F.Viallefond).
The committee stresses that the design
is a global process so that all configurations should be matched together.
A possible working scheme is to define the COMPACT configuration first,
and to progress continuously to the most extended one. This requires proper
collaboration between the various participants to the effort.
