Minutes

  • Wiki is set up and linked to in the main SBS wiki page. People should add to it as they see fit.
  • What is the density in the pumping chamber? PC/TC signal ratio = 0.21,0.22,0.23 recently. VERY important ratios.
  • Want a spreadsheet that contains every single measurement taken with all settings written down.
    • We need to know the status of the beam for each measurement.
    • TO should include information about the beam status when they take measurements. Maybe they can include a screenshot of the beam live plot?
  • We see large change in signal with magnets off vs magnets on. We need to identify what causes this change.
  • Results shown by Hunter today:
