  • Lab Update
    • 1K pot started with no issues.
    • Base temperature hit 33 mK and stable, so switched to Tower thermometer.
    • Removed one set of thermometer wires connecting 1K pot, Still etc and only monitoring MC temperature (as well as tower).
    • Added more mixture since the base temperature is higher on Monday.
    • Tower seems to be adding more heat even when we are not actively reading it.
    • Checked SQUIDs using new DAQ, thanks to Shubham to get the PulseViewer ready.
    • With DCRC on, MC went from 33 mK to 40 mK, tower went up by 40 mK (120 mK to 160 mK).
    • Since Rp and Rn measures 40 mohm, it seems normal and tower might be reading correctly.
    • Noise PSD on PES2 shows 60 Hz, 120 Hz and a forest around 120-180 Hz.
    • We unplugged the other thermometry cable to see if we can see a lower noise level and the noise forest got a little lower, although peaks remained.
