The size of this is to be determined taking into account the scope of the proposed radiobiology programme. ○ AK to ask ZN and OE to specify total footprint of the laser and shielding requirements. • Parameter table ○ JPo: Parameters in the table will define the physical geometry of the Gabor lens and the nominal operating voltage. This is sufficient info to generate a field map (for tracking). § KL: What about alternative technologies, i.e. solenoids. § Following some discussion, it was decided that the equivalent solenoid field strength and lengths of the solenoids should be included in the parameter table. ○ Beam transport § Details in the parameter table should define the input and output beam. § AK to discuss with JPas. ○ Stage 2 needs to include another end station (also define the input and output beams). ○ End stations - JPar. § 30mm beam size would be better than 10mm. □ AK: to follow up with JPas. § Platform and robot for multiple irradiations. § Clatterbridge experiments can go through 130 dishes at a time. • Status updates ○ Proton capture - JPo § COMSOL needed for the EM simulation of the Gabor lens. § Would be good to also do the plasma simulation in COMSOL. § AK got a quote from COMSOL. Looking into options for reducing the cost. ○ Beam transport - WS § GPT studies to verify tracking with and without space charge. • Instrumentation ○ PPD will provide input to this. ○ For the baseline, include a statement of the need for diagnostics and how they will be used, e.g. during commissioning and running. • AOB ○ KL: Steering group set up. Will have SG meetings. § Add SG meetings to the wiki. = Action Items = • JPo, CW, ZN and OE to meet to discuss details at the laser/proton capture interface. • AK to update the interfaces documents to clarify areas where there are overlaps in the components. • AK to clarify on the wiki what needs to be delivered for 29/11/19. • AK to ask ZN and OE to specify total footprint of the laser and shielding requirements. • AK to add solenoid details (from the GPT input file) to the parameter list document. • AK to discuss with JPas what parameters should go in the parameter table for the beam transport. • AK to note the instrumentation requirements for the definition of the baseline. • AK to add details of the steering group meetings to the wiki.
