%X Measurements of the charged particle multiplicity produced in proton-proton collisions at the LHC at centre-of-mass energies s**(1/2) = 0.9-TeV and 7-TeV recorded with the ATLAS detector are presented. Distributions are presented for events with at least one charged particle n(ch) >= 1 in the kinematic range  - eta -  < 2.5 and p(T) > 500-MeV. Measurements have also been made in a diffraction-limited region of phase-space n(ch) >= 6 and used for the production of the first Pythia6 tune to LHC data, the ATLAS Minimum Bias Tune 1 (AMBT1).
