Agenda

• Action items from last meeting.
  • None
• System updates.
  • Laser driven proton and ion source.
  • Proton and ion capture.
  • Stage 1 beam transport: Beam transport and delivery to the in vitro end station.
  • Stage 2 beam transport: Post-acceleration and beam delivery to the in vivo end station.
  • Biological end stations.
  • Infrastructure and Integration.
  • Project plan for the delivery of LhARA.
  • Safety.
  • End-to-end simulation.
  • Instrumentation.
• R&D plan and schedule.
  • Version 2 xml or pdf

Notes

• Participants: AK, HTL, KL, TD, OE, WS, JPas, CW, GA.

• Status updates
  • laser - OE
    • ZN proof reading but he's on strike.
    • Costings being prepared.
  • Capture
    • Update in Overleaf.
    • Titus to add detail on diff pumping.
    • CW to work on the R&D part.
  • Beam transport - WS.
    • Focus has been on the write up of v4.3 as the main design and v5.3 as the alternative design.
    • Simulation using a more realistic beam will be done.
    • Ready for feedback.
    • AK to go over this.
    • JPas
      • Looked at tweaking 4.3 to reduced Beta from ~400 to ~50 to facilitate injection.
      • This change moves the focal point for collimation to where the RF cavity is.
      • This would increase the space needed after GL5, for octopoles, cavity and the switching dipole.
    • HTL
      • Updated Overleaf with the transfer line to in vivo.
      • This is more or less complete. Simulations from after RF cavity to the end station as assuming alpha=0 after extraction line.
      • Overleaf has many plots not included in the document. Can decide later what not to include.
      • Inconsistency in the BDSIM simulation being investigated.
      • Beta=58 coming out of extraction translates to 1cm for 15MeV, 3cm for 127MeV assuming 10x emittance growth.
      • AK to look at the write up on Thursday when it'll be ready.
  • GA
    • The costing has been updated based on costs from other existing facilities.
  • Pre-publication review of the pre-CDR - KL
    • Proposed agenda (see attachment) will be circulated.
    • 20 minutes for each speaker should cover 10 minutes for a presentation and 10 minutes for questions.
