Updates from last meeting action items

• Gabriel: Working with Max, they benchmarked the CST model with POISSON in term of electric field distributions.
• Alicia
• Max: Evaluated cathode geometry (Attach Max's summary document here)
• Carlos

Items for discussion

• Modeling
• Parameter space

Action items for next meeting

1. Define electrode hole size. We chose Tee electrode diameter = 12.82 mm (0.5047 inches). The wafer is 15x15 mm. Joe said to choose the present R28-2 CEBAF gun electrode hole diameter. DONE
2. Max. Study focal length and spherical aberrations using field variations
3. Max and Gabriel (who is making the table?) Generate a table of parameter searches that includes: GaaAs plane position wrt to the electrode hole plane, Angle of GaAs plane, laser size, laser position, bunch charge.
4. Gabriel to work with Keith on finding the GaAs position range
5. Carlos to create wiki page (in progress)
