Abstract

Recently the ATLAS experiment was complemented with a set of ultra-small-angle detectors located in ``Roman Pot'' inserts at 240m on either side of the interaction point, aiming at the absolute determination of the LHC luminosity by measuring the elastic scattering rate at the Coulomb Nuclear Interference region. Details of the proposed measurement the detector construction and the expected performance as well as the challenges involved are discussed here.
