Title        :  Storage ring problems
Author List  :  D. Trbojevic and C. Johnstone
Abstract     :  
		The muon collider storage ring requires larger momentum
		acceptance due to uncertainty of the incoming beam momentum
		spread. The momentum spread depends on muon cooling and
		acceleration abilities. The zero momentum compaction
		storage ring is built by the Flexible Momentum Compaction
		(FMC) lattice method described earlier [1,2,3]. The maximum
		dispersion in the arcs is the order of ~0.3 meter, while
		the maximum of the bending field is ~ 5 T.  The collisions
		are assumed to be at energy of 250-250 GeV. The small
		“Higgs” muon collider has an arc of 200 meters in
		circumference and momentum acceptance of dp/p~+-8-10 %.
