Notes

Present: CW, JPas, AK, WS, GA, KL, JPar

• Action items
  • CW: No response from others, will try again.
    • Main issue is to determine how close to the target the first lens can be and provide options for differential pumping, shielding against activation, route out for the laser, etc.
    • AK will try to arrange a meeting this week.
• JPas: Chris Rogers suggested using a solenoid lens to separate electrons and protons.
• Floor plan
  • End stations: Only other detail is reconfiguration for 2 end stations.
  • JPas: independent extraction ports for the FFA. Would affect cost.
    • AK: Could increase foot print.
  • AK: details of the extraction.
    • Should add this on the floor plan update.
  • JPas: no dispersion matching for injection into FFA.
  • AK: is there any additional floor space needed for the in vivo experiments?
    • JPar: The existing box on the ground floor is fine for the irradiations.
    • AK: Any updates on the holding facility?
      • JPar: spoke to Mark Hill, won't need much space for the holding facility. Goal is to have a small space. Shouldn't need to be included in the floor plan, can just have this as a comment in the pre-CDR.
  • AK: Capture section may need to add power supplies.
  • AK: Beam transport. Need details to work out floor plan.
  • JPas: don't have spec for in vivo beam.
  • JPar: Depends on what experiments are being done. Would like a range of beam sizes.
    • JPar: to define beam specs for in vivo experiments.
  • GA: Looking at expanding on the WBS. Want to see laser safety to pare down safety case from ISIS level of detail.
  • KL: Need to include access.
• WBS
  • JPas: Abort line should be on the floor plan.
• Parameter table
  • Needs to include sufficient detail to define the baseline.
  • Including details on collimators, rebunching cavities, spaces between
  • CW: Should add charge density.
    • JPas: and magnetic field, collimator
  • AK: What would be the lowest extraction energy that would be of interest.
    • JPar: 15MeV in vivo would be for very superficial tumours.
  • AK: level of detail for the FFA
    • JPas: Need more detail to be able to fully define the magnet such that a designer can do an engineering solution.
• AOB
  • KL:
    • RFI talk went well. Hopeful that we may get endorsement of the concept in the future.
    • IBC have arranged a special edition of a nuclear physics journal and we have been invited to submit an abstract. Deadline early December.
    • Also IPAC, PTCOG, APAC.
    • AK to prepare list of the 4 abstracts needed. One abstract, 4 different "spins".
    • SG meeting on Thursday. AK will present baseline design.
    • AK to draft outline R&D plan and circulate for comments before Thursday.
