Superconducting dipoles and quadrupoles for a 2 TeV muon collider

Abstract

At 2 TeV the mean lifetime for a muon is 41.6 ms. In order to achieve high luminosity at the collider collision point, the dipole central induction for the storage ring should be over 8 T. The storage ring carries muon over 1000 turns through the ring before they decay away. Muons decay to two neutrinos and an electron or positron (depending on the charge of the decaying muon). Seventy percent of the muon energy will be taken away by the neutrinos. The electrons (at average energies of 700 GeV) and the photons (at energies up to 2.1 GeV) are quite penetrating. At the design luminosity of the muon collider, the superconducting dipoles and quadrupoles in the storage ring must contain muon beams (up to 1.4/spl times/10/sup 14/ muons per second) that will deposit over 1.8 kW per meter of energy into the storage ring. This report presents two design approaches for superconducting dipoles and quadrupoles that can be used for the muon collider storage ring.
