Meeting ID: 902 449 7080
Domestic: 1-408-638-0968 (US toll)
Access code:
  • Lab Update - Run 82 preparation
    • Fridge Status : Fridge is at base temp of 57 mK, Tower at 124 mK
    • SQUIDs are tuned. All 6 channels show SQUID modulation.
    • new DAQ Test: Yan and I looked hooked up the RevE Board to look at SQUID modulation. Initially the daq was failing after a few minutes due to too many stale triggers, but Yan solved the issue.
    • We are not able to see SQUID modulation. We can see triangular wave pattern from the signal generator. The TES numbers seems mismatached. We expect TES0,1,2,3 and TES5,6,7,8 to show traces, but the Pulse Viewer show 5 active channels and not mapping with the expected TES numbers. This indicates some kind of mixed channel mapping or pin mapping, given we donot see SQUID modulation. We will work more on the new DAQ once Yan is back.
      • Channel mapping from Shubham:
    • I dont see a adapter to quick connect the He3 cylinder to add more pure He3. I will look for one at other labs tomorrow.
    • Plan is to take Q_dot data.
