Questions from NuFact’15 NuFact'16, August 22-27, Quy Nhon, Vietnam

NuFact'15, August 10-15, CBPF, Brazil Target/capture MW-class targets are still of major concern in neutrino beams. While carbon target is been pushing to the limit, fluidized solid target is still a developing concept. New questions: Will fluidized powder or granular target work? 8/10/15 NuFact'15, August 10-15, CBPF, Brazil

NuFact'15, August 10-15, CBPF, Brazil Muon Acceleration Staged muon acceleration schemes have been developed well within MAP and NF-IDS. No specific questions passed to this workshop 8/10/15 NuFact'15, August 10-15, CBPF, Brazil

NuFact'16, August 22-27, Quy Nhon, Vietnam MICE MICE started collecting data in Step IV configuration New question: what would be the best way to present results obtained by next year NuFact'16, August 22-27, Quy Nhon, Vietnam

NuFact'16, August 22-27, Quy Nhon, Vietnam nuSTORM/nuPIL Should the workshop expand its emphasis and consider extensions to conventional neutrino beams moving beyond horn-focused beams? What Is the physics performance of non-conventional neutrino beams? Can a muon-based neutrino beam be operated parasitically to a high-power pion-based neutrino beam (nuPIL)? NuFact'16, August 22-27, Quy Nhon, Vietnam

NuFact'16, August 22-27, Quy Nhon, Vietnam Muon experiments What are the optimum beam designs for next generation muon experiments based on current and future proton beams? (inherited from Nufact14) Discussion needs to continue with more interaction between WG3 and WG4 New questions: What are the possible applications of cooled muon beams? Can we design the capture/front end system, which would be beneficial for many experiments? NuFact'16, August 22-27, Quy Nhon, Vietnam

NuFact'16, August 22-27, Quy Nhon, Vietnam ESS For low-energy nuSTORM at ESS: Should it be based on a storage ring or a straight channel (like MOMENT)? NuFact'16, August 22-27, Quy Nhon, Vietnam

NuFact'16, August 22-27, Quy Nhon, Vietnam Summary We have a full WG3 agenda 27 parallel talks and four plenary talks We will address the questions passed from NuFact’15 Other questions will be discussed during the workshop and at the summary preparation session on Friday NuFact'16, August 22-27, Quy Nhon, Vietnam
