This report describes studies performed in the framework
of the Collimation Task Force organized to support
the work of the second International Linear Collider Technical
Review Committee. The post-linac beam-collimation
systems in the TESLA, JLC/NLC and CLIC linear-collider
designs are compared using the same computer code under
the same assumptions. Their performance is quantified in
terms of beam-halo and synchrotron-radiation collimation
efficiency. The performance of the current designs varies
across projects, and does not always meet the original design
goals. But these comparisons suggest that achieving
the required performance in a future linear collider is feasible.
