Access code:
  • Lab Update
    • Tower slowly reached 75 mK this morning.
    • RevC Pulseviewer not working. I took two datasets without squid biased and one dataset with squid biased to see IbIs and noise.
    • Zapped SQUID:
      • Before:
      • After :
    • Shubham processed the IbIs dataset but it is showing sinusoidal pattern.
      • Before zapping:
      • After zapping:
    • IbIs curve after zapping with RevE:
      • 1000 to 300 uA :
      • 500 uA to 0 uA :
    • Noise with RevE:
    • The noise profile on other datasets need to be processed, but a manual look with RevE showing applying QET bias current leads to change in overall noise plateau.
    • Note:
      • RevE DCRC injects more heat than RevC. Tower temperature goes to 145 mK from 75 mK when we connect RevE, while RevC shows no visible change.
