Beam halo scraping schemes have been explored in the 50{times}50&hthinsp;GeV and 2{times}2&hthinsp;TeV {mu}{sup +}{mu}{sup {minus}} colliders using both absorbers and electrostatic deflectors. Utility sections have been specially designed into the rings for scraping. Results of realistic STRUCT-MARS Monte-Carlo simulations show that for the low-energy machine a scheme with a 5 m long steel absorber suppresses losses in the interaction region by three orders of magnitude. The same scraping efficiency at 2 TeV is achieved only by complete extraction of beam halo from the machine. The effect of beam-induced power dissipation in the collider superconducting magnets and detector backgrounds is shown both for the first few turns after injection and for the rest of the cycle. {copyright} {ital 1998 American Institute of Physics.}
