Memo on Hybrid Array
Hybrid
Configuration pad positions.
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:
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.
