Notes

Participants: AK, WS, HTL, JPas, KL
Apologies: CW, GA
Guest: JB Lagrange

• Action items
  • Talk to OE and GH. KL and HTL spoke to ZN and may help out with the Smilei.
  • Electric field. KL to look into this too.
    • Focussing strength for electric field in IPAC 2019 paper . See wiki.
  • CW circulated to few
    • AK to add to wiki.
• System updates
  • Beam transport
    • WS: Stage 1 simulations using idealised and realistic beam. Good transmission with idealised beam and version 4.2 of the lattice.
    • JPas: Arc has been redesigned to eliminate simultaneous minima in both planes to be used with v4.2 lattice arc
      • Details on Stage 1 redesign: now has 3 lenses and 4 quads.
    • Stage 2 - JPas
      • Details of injection being worked out.
    • JPas to send AK beta and alpha as a function of S (calculated by BeamOptics).

Action Items

• AK to add Colin's note to the wiki.
• JPas to send AK beta and alpha as a function of S (calculated by BeamOptics).
