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. == Action Items == * AK to note the instrumentation requirements for the definition of the baseline. * OE to circulate what was done for safety case for the laser in 027. * AK to arrange meeting between laser and capture WPMs. * JPar to define beam specs for in vivo experiments. * AK to prepare list of the 4 abstracts needed. One abstract, 4 different "spins". * AK to draft outline R&D plan and circulate for comments before Thursday.
