Centerstack Tile Analysis (Boales)
see VGs
Initial
stress analysis of the centerstack tiles has been performed. The run
included thermal, halo current and eddy current loads on the tiles on the CS
cylindrical section. The results indicate the stresses in the CFC
material is low, approximately 10% of the allowables (2D material). This is
good news and allows the use of the less expensive CFC materials in this area
as planned.
Diagnostics Space and Coil Structures [Smith
(see VGs) ]
Mark
Smith presented the PF and OTF structures to begin discussions with diagnostics
on the best way to plan and coordinate installation of the structure to
minimize the impact to the existing installations. Several methods of
dealing with the work were discussed including detailed modeling of the
diagnostics, coarse simplified modeling of the diagnostic locations,
metrology to document and map the diagnostics, and photographic study of the
area. Brent Stratton has provided a Diagnostic Port assignment drawing to
help identify the diagnostics locations. Mark Smith will be providing
models of the structures for use in installation planning.
Mike
Viola will take the lead to work with diagnostics to develop a plan for the
installation of the structure.

Outstanding Action Items (last update 6/17/2010)
Update SRD is around for approval. The
idea of a Design Load Requirements (Criteria) Document is a good one. Action:
Mark Smith to pull this together for the Structures– Need this BEFORE the PDR
Action: We
have a set of Calculations signed off, but not all were checked for the CDR. These
calcs need to be updated and checked (by PDR?). ACTION: Titus
