Meeting Info
We will meet on Wed (UAS 9am, JLab 11am, IJCLab 5pm) Bluejeans: https://bluejeans.com/405130883/4307 Code to start the meeting 4307
Aug 4 Agenda
- Mark's presentation
- schematic of layout
- fraction of e+/e- beam
- include e- (need Geant4 + standard GPT)
- Why PAC proposals might fail?
- Arguments that reversing CEBAF dipole polarities is problematic or costly
- Arguments for a cold start tune-up of CEBAF with low current (10 uA peak @ 60Hz: VL~6e-4 = 6nA ave, BPM~1.5e-2 = 150 nA)
- Arguments for realistic multi-pass acceptance
- How do we coordinate our efforts?
- Mark develop start-to-end model
- Sami explore beam size/angle Geant4
- Andriy will work on target
- Ryan exploring FFA concept
Jul 28th Agenda
- Positron parameter tables:
- Discussion
Meeting Notes
- Small meeting with Eric, Riad, Ryan and Mark
- Bunch length needs to be confirmed, north linac fractional energy spread acceptance needs to be checked, emittance is a concern
- possibility of FFA use given the wide energy/momentum spread
- presentation with table values explained and simulations is being worked on
