  • 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.
  • Pre-publication review of the pre-CDR.
  • A.O.B.


  • 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.
