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:
- What to do next:
- Gordon is not in favor of raising the oven temp.
- We have 4 points at 9V, let's drop down to 8V to see if there's a change.
- Look at laser spectrum. Is it optimized? Are the temperatures where we think they are? (Jack and Todd will work on this)
- Raise laser from 160 to 180 once we've looked at the laser spectrum.
