Discussion Topics How to transform Project X into a Proton Driver? Should linac be CW or pulsed? How many IR’s? How promising are new Induction Accel. ideas? MANX, MICE, & the 5-year plan Will MC be low, med, or high emittance? What were the highlights of this workshop? Questions about particular talks December 12, 2008 Chuck Ankenbrandt Muon Collider Design Workshop

Scaling of Muon Collider Requirements The luminosity of a muon collider is given by the product of: the integrated luminosity per muon bunch pair injected, times the rep. rate Rb of injecting bunch pairs into the collider. Designers often assume (optimistically?) that the muon bunches can be made bright enough to reach the beam-beam limit. Then: and for given luminosity, energy, and beam-beam tune shift: the rep. rate scales inversely with the trans. emittance; the proton beam power is independent of the trans. emittance.
