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.

• • updated with shaped electrode media:28Feb2020Vacuum.xlsx

• Josh - compare GPT routine using tee-geometry between (as-is, preserve neutral energy, w/ space charge)
  • Analysis of the energy transfer equation for an electron-neutral collision from Vahedi and Surendra (based on Atomic Collisions by McDaniel)

• Joe - 1,1.5,2.0 milliamp runs summarized media:200228_spot_size_run_summary.txt

• Carlos - GTS ion simulations media:200228_Ion simulations in GTS by Cristhian Valerio jlab2018.pptx
