  • Lab Update
    • More cryo drama. After partial warmup to remove helium from IVC, can't cool below 4K. Probably due to two procedural errors:
      1. Left the DCRCs on during initial LHe transfer and overnight after that. That warmed the base to >10 K overnight - surprising. Took a couple days to figure out that was the problem. Couldn't get the 1K Pot to cool it.
      2. Left 1K Pot open to Main Bath during partial warmup. Now 1K Pot doesn't work, must have ice in it.
    • Warming up again to fix 1K Pot
  • piZIP concept (Matt). Matt Pyle's piZIP presentation
  • General Updates
