Description
The LHC aperture for the perfect machine and its dependence on various
optics imperfections are discussed. The optics tolerances required to meet
the desired performance of the LHC collimation system are given. These
studies are based on the results of tracking simulations of the beam halo
and on a detailed aperture model of the full LHC ring, with spatial
resolution of 10 cm over the total length of 27 km.
Experimental results from the collimator tests with beam at the SPS are
reviewed and specific issues related to the commissioning of the
LHC collimation system are discussed.
