05:18 PM Runs Task #24877: DR_1_Run_8
estimation of TI-1 Q from decay (slightly better than TI-2)
decay time from -64 dB to e times (green line) = 39 ms
...
05:01 PM Runs Task #24877: DR_1_Run_8
We found the resonance of RI-1,
freq = 2.985951150 GHz
Mixing chamber temperature = 65 mK (It is increased a little...
04:45 PM Runs Task #24877: DR_1_Run_8
Some more accurate estimation of TI-2 Q from decay:
decay time from -50 dB to e times (green line) = 32 ms
Q = pi *...
