Muon collider interaction region design

Design of a muon collider interaction region (IR) presents a number of challenges arising from low β*<1 cm, correspondingly large beta-function values and beam sizes at IR magnets, as well as the necessity to protect superconducting magnets and collider detectors from muon decay products. As a consequence, the designs of the IR optics, magnets and machine-detector interface are strongly interlaced and iterative. A consistent solution for the 1.5 TeV center-of-mass muon collider IR is presented. It can provide an average luminosity of 10³⁴ cm^-2 s^-1 with an adequate protection of magnet and detector components.
