Subject: Conference call 2 PM Eastern time Monday, June 21 to discuss fracture requirements and cable fatigue testing - WITH Attachment this time!

Sorry...here's the attachment!

Please join a conference call at 2 PM Eastern time Monday. PPPL folks - we'll meet in the ME conf. room. (Marianne-will you please reserve it for me for 2 to 4? )

Agenda;

Discussion of fracture requirements and what our next steps should be - please see the attached slides that we'll discuss during the call. Additons to the slide set, other opinions, etc, would be much appreciated. If you have any additions , please send them to the entire group and copy meconf@pppl.gov by noon.
Update on the cable fatigue testing at LN2 temperatures. Good news - it's achieved 20 X life. We'll also disuss if we should continue to test this sample to failure. If so, shold we continue at the same load or increase it? Here's a note from Tom Kozub concerning the status:

"Yesterday we concluded the 2.6 million cycle test on short race track coil sample SRT3 at LN2 temperature. The resistance remained constant throughout the testing. After the initial 150000 cycles, the legs stretched about an additional 0.010 in. during the remaining 2.45 million cycles. The modulus was reduced by about 1/2 over those same cycles. The sample is now warming up and visual inspection will take place once it is de-iced."

Thanks!
Phil
