• Previous action items
  • AK to note the instrumentation requirements for the definition of the baseline.
    • Done
  • OE to circulate the blank risk assessment form.
    • Done
  • AK to arrange meeting to discuss the laser target interface.
    • Doodle poll created. Date will be finalised soon.
  • JPar to look into spot scanning beam specs for in vivo experiments.
    • Stands.
  • AK to prepare abstract for upcoming abstract deadlines.
    • JPas circulated abstract for IPAC. Other abstracts will follow on from this.
  • AK to ask Simon for a repository to store the simulation input files.
    • Done.
• System updates
  • beam transport - JPas
    • Working on definitions of the FFA.
  • beam transport - WS
    • Simulations for stage 1 and comparisons with BDSIM and GPT
    • transmission goes from 1% for q=1e9 to 25% for q=1e8.
    • Issue with beam definitions.
  • Infrastructure and integrations.
    • Ian from TD will prepare the updates of the floor plan.
    • AK: need to start thinking about costing.
    • Have order of magnitude guess. Can use existing projects to get comparison of costs.
    • GA: what does Instrumentation cover.
    • AK: Definition at the bottom of the pre-CDR preparation page Research/DesignStudy/PreCDR.
    • Controls and monitoring included in integration but may want to include fast feedback specific monitoring in instrumentation.
    • GA: JT spoke to CLF and will follow up.
  • Simulations
    • Fix on using ROOT as persisted format. Provide conversions for other formats.
    • JPas: BDSIM simulation through to injection septum. FFA. Septum to end station in BDSIM.
    • KL: interface at the switching magnet?
    • Discussion on best location of the interface.
    • Interface at input to the septum and extraction after septum.
    • AK: Will prepare a wiki page for simulation.
