== 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 about HTL helping with the Smilei simulations.
  * 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).
