Notes

Participants: AK, GA, JPar, HTL, WS, KL, JMat
Apologies: JPas

  • Action items
    • JPas to send AK beta and alpha as a function of S (calculated by BeamOptics).
      • Stands
  • System updates
    • Laser
      • AK to arrange meeting to discuss R&D plan and write up.
    • Capture
      • Meeting on Friday with Colin and KL to discuss R&D plan.
      • KL: Arranging meeting to coordinate the work.
    • Beam transport
      • WS: Updating Stage 1 design to get alpha to 0.
        • Couldn't find solution.
        • Lattice CCAP-v5 gives an elliptical beam in the end station.
        • Looked at updating previous lattices.
        • Using octopole after lens 5 (which now must be a solenoid) gives a more uniform distribution.
      • AK to arrange meeting to discuss writing up.
      • HTL:
        • JPas looked at HTL's design in BeamOptics. Beta was getting very small in places.
        • Looking for new solution to avoid this. Found minimum beta of about 1cm but this may still have problems with space charge.
        • HTL to look at simulating this using GPT.
    • End stations - JPar
      • Waiting on finalising the beam line before updating floor plan.
      • Discussed R&D plan. For the end stations that is automation of placing samples in the beam line.
      • Collaboration with Birmingham. Currently looking for space to build lab there.
      • Will do preliminary flash research in the next few weeks
      • Kristoffer Petersson, now at Oxford was Lausanne, working on FLASH. Look to collaborate. They have a flash electron machine, which would complement our protons.
      • Will hopefully go to Manchester on the 5th March.
    • Infrastructure and integration - GA
      • Updates to layout waiting on design being finalised.
      • Started writing.
      • Spoke to CLF. Have a paragraph on safety from them. References to existing lasers. Other issues will be solved with EPAC.
        • CLF mentioned shielding should be between target and laser room to allow work on the laser outside the radiation area.
      • Progress with costing. Should have something to circulate on Monday.
      • GA to circulate template spreadsheet for costing to WPMs.
    • Instrumentation.
    • R&D plan
      • Meetings with WPMs to update details.
      • Should be completed Monday next week.
    • Write up
      • Review write up in Tuesday meeting next week.
