An IR and Chromatic Correction Design for a 2-TeV Muon Collider’, to appear

To obtain the design luminosity of 1035 cm2s1 for a 2-TeV muon collider[1], considering the projected muon production rate[1] and lifetime, demands very low -function values at the IP; a of 3mm. This very small is particularly difficult to achieve because the superconducting magnets must be heav-ily shielded from the decay products of the muon beam and be-cause space must be reserved for the detector about the interac-tion point, thereby reducing further quadrupole gradients which are already weak for 2-TeV muons. The Interaction Region and its chromatic correction remain one of the major challenges of the muon collider lattice design. I. GENERAL DESCRIPTION Fig. 1 gives the layout and lattice functions of an Interaction Region (IR) design with a of 3mm for a 2-TeV muon col
