  • Lab Update
    • Data taken up to +75V and -75V. Continuing trend of higher drift rate needed at higher bias, steeper slope in -bias
    • Luke gain looks pretty similar in - and + polarities so far - not yet seeing the strong polarity dependence noticed in previous runs
    • Temperature rises several mK after LHe transfers and LN2 fills, then slowly settles, making it hard to take consistent data
    • Studying whether to add more 4He to mixture
  • General Updates
