Agenda
- Marcy - From last's meeting's post => media:21Feb2020Vacuum.xlsx
This is the pressure vs. distance profile for my first try at vacuum simulation for the gun through the anode and into the y chamber, with about 3-5% CO, no methane, the rest is H2. The pressure in mbar is 2.5e-12 mbar, or 1.8e-12 Torr in the simulation. I have a scale factor included in the spreadsheet to adjust for the pressure measured, which is ~8.5e-12 Torr.
