• Simulations
  • Slides from JP
    • Analytic field map with doublet FF focussing.
    • Able to obtain the initial working point.
    • Constant tune as a function of KE.
    • Betatron functions.
    • New parameter list.
    • New lattice allows for large variation of vertical tune.
• CAD
  • Details shown by CH on the layout of stage 1.
    • JP: Distance between len 3 and 4 is critical. Distance between lens 2 and 3 can be adjusted.
  • Further work on the target chamber shown by CH.
  • NB: Progress on FETS FFA engineering details. These details are relevant for LhARA.
    • CH is looking at the vacuum chamber.
    • Need to have strengthening ribs and bellows.
    • This requirement has led to an increase in the magnet gap size.
• NB: Costing
  • Looking at adding detail to the costing detail used in the PA2 proposal.
  • Discussion.
• AOB
  • JP: question for CH. What is the size of the wall after lens 2 and is there a shutter?
    • Nominally 0.5m
    • Is the gap on the current diagram sufficient?
    • Need to do a radiation study.
    • The size of the wall is important for the injection line.
  • RR: Message from WS re submitting an abstract for the NPL workshop.
    • Consensus is if WS can submit one then that is good.
