Agenda

  • Action items from last meeting.
    • WS to send JPar snapshot of beamline.
  • 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.
  • A.O.B.

Notes

Participants: AK, WS, JPas, KL, Jpo, HTL, CW
Apologies:

  • Laser
    • Input beam produced by HTL. Try to get OE to take a look and ask about progress with 3D simulations.
  • Capture
    • JPo: Will get different focal points for both solenoids and Gabor lens when using a beam with an energy spread.
    • JPas: will calculate electric field matrix for Gabor lens.
    • CW: more work on electric field modelling. Looking at breakdown, current design should be resistant.
    • CW: differential pumping calculations updated now have 3 orders of magnitude pressure drop. Need to get input from the laser guys.
    • CW to circulate document.
  • Beam transport
    • JPas has updated the stage 1 lattice.
    • Simulation files have been updated to include 5cm without space charge and 5cm with space charge and then run in BDSIM and GPT.
    • Rebunching cavities for stage 1:
      • 1st cavity is for phase rotation.
      • Collimator between lenses 3 and 4.
      • 2nd is for rebunching after lens 4. (to rotate and shorten bunch).
  • R&D plan due in 2 weeks. AK will circulate the Initial draft.

Action items

  • Discuss input beam with OE and GH.
  • JPas to calculate electric field matrix for Gabor lens.
  • CW to circulate document on laser capture interface.
  • AK to circulate initial draft of project plan.
