Jim,
 
Can I assume that you consider this RFA closed now?

Mark,

Much more appropriate response.  I also agree with adding this to the Project Risk List.  My biggest concern is not necessarily the bulk stresses of the grid--> it is pretty beefy.  Rather, it is the interface stresses for the Radiator, Tracker, Calorimeter, ACD, etc.

Jim,

Attached is an updated RFA response to LAT CDR #10, based on your comments.

I also wanted to let you know that we have recently added this to our Project Risk list which is statused every 2 weeks.  One of our mitigations is to compare the grid tensile data from the samples cut from each billet.  The sample from billet #1 was taken after the straightening was performed.  We have received the tensile data from the first billet and will receive the data for the second billet in a couple of weeks.  The data for the first billet meets the minimum ASM properties for T6.

Please let me know if this addresses your concerns.

Thanks,

Mark

Mark,

My comments can be found in the attachments.  In short, I believe some more information concerning risk should be added to CDR #10 response if qualification of the Grid structure is to occur on a "spare" Grid.  CDR responses #'s 11 and 15 are acceptable.

Please let me know if you have any questions.

Jim Ryan

Jim,

Attached are 3 responses to RFAs you wrote at the GLAST LAT CDR.  Mark Goans, the Code 300 Review chair, has asked that all Project approved RFA responses be reviewed and approved by the originators prior to official submittal to him.

Please review the attached responses and let me know if they satisfactorily close the RFAs you generated.  You can provide your approval or comments back to me and I will distribute them to the appropriate GLAST Project personnel.

Responses are attached for the following RFAs:

GLAST LAT CDR # 10, 11, 15

Thank you for your review and response,

Mark
