Run Diary
10:52:26.4
Temperature starts to drop. Wait for temperature to stabilize.
Take traces Run001 to Run004.
11/18/2009 12:08:52 PM
Temperature fluactuates around 35.7 mK
11/18/2009 5:02:22 PM
Temperature stabilizes at 33.9 mK. Fridge is grounded to the orange ground. Try to take more noise traces.
Take traces Run005 to Run008
There is no difference in noise psd when the fridge is grounded to the orange ground. Try taking IbIs data to check Ic.
11/18/2009 5:56:42 PM
Take IbIs data Run009 to Run012
19:07:36.4
MC temperature went up to 48 mK and drops at 19:13:27.7
11/18/2009 8:29:04 PM
Take psd Run013 to Run016 with DCRC shielded.
Shielding DCRC doesn't make much difference.
