Notes from 5/11/2011 Meeting:
Review of Calc Spreadsheet 
Design Point Spreadsheet added to list (#10-03-00). Still needs to be checked, Action: C. 
Neumeyer to provide checked calc.
Ron Hatcher emailed out copies of the Force Influence Coefficients this week to complete that 
item (#13-03-0).
Heat Balance Calc is in final review (Brooks incorporating comments)


VV Thickness for MPTS   (Labik) (see VGs)
From the MPTS PDR last week there was a chit concerning the asymmetry caused by the bay K 
VV mods.  The asymmetry may affect the RWM and PF fields enough to impact machine 
performance.  Labik has asked Stefan to look into the affects and Mark Smith to run a simplified 
analysis using a frame instead of plates for the reinforcement. Results should be available in the 
next week or two.


PP Analysis Check Update (Zhai) (see VGs)
Yuhu is running a 3D Opera analysis to benchmark the Titus analysis shown last week.  The first 
funs don't include the detailed connection to the VV through the brackets but instead a short SS 
section between plates.  The results so far are around 10% different than the Titus results.  Will 
be putting in the details of the VV connections and rerunning the analysis.

Lower Lid and Pedestal (Titus) (see VGs)
The lower lid stress is okay but could be improved if the jog in the radial arms could be removed. 
 The lower lid stiffness is low compared to the original solid lid.  The pedestal to the floor 
connection needs to be securely fastened with anchors to ensure that the torque can be 
transmitted.
