Roundtable Discussion on Future Machines – Quy Nhon, 14.08.2014
• Introductory presentations (20’)
• Discussions (30’):
1. Do we need precision or/and high energy? How precisely do we need to measure various couplings? How many Higgs decays, how many Z decays should be produced? Which energy should we aim for?Which collider has the strongest physics case after the HL-LHC?
2. How can we make sure that the wishes of the physics community are synchronized with the technical developments in the accelerator sector? How mature are the technologies for hadron collider, circular or linear e+e- , and other colliders?
3. What risks do we have for reaching the announced performance levels for hadron collider, circular or linear e+e- collider (or gg or muon) collider?
How long will the commissioning take? 5
4. Can one extrapolate the “LHC” collaboration models to the next machine?
5. To what extent should the choice of the next project be driven by a long-term strategy?
• Concluding remarks (5’)

hadron-collider peak luminosity vs. year
LHC run 1 (2012-13) accumulated more integrated luminosity than all previous hadron colliders together!
“Of course, it should not be the size of an accelerator, but its
costs which must be minimized.”
