Attached are some files illustrating a proposed test sequence.  I am assuming a 5 day test, including 1 day at each end for cooldown/warmup.

 

Day 1 - cooldown

Day 2 - low current tests -calibrate resistance, inductance compared to calculations, re-do day 3, 4 plan

Day 3 - run up the current in increments, no ratcheting in temperature

Day 4 - run up the current and take extra shots at full current, allow ratcheting to 85K

Day 5 - warmup

 

I am resending the original test plan, some pdf files showing the proposed test sequences, and some plots illustrating the current/voltage/temp waveform at 31.5 kA, with and without the production coils for comparison.

 

Kevin re-ran the TRC analysis with the strain gages in the new  locations, so we should have charts of strain prediction to go with this soon.

 

I will plan to show up at PPPL on Monday morning, Aug 15.
