description Previous results for the prospects of B_s mixing measurement in the ATLAS experiment at LHC are updated. The improved analysis method of the studied decay channels B_s -> D_s pi and B_s -> D_s a_1, combined with most recent values for the branching ratios and the B_s lifetime, leads to the new ATLAS sensitivity range for the x_s measurement: x_s~{max} = 42. An extensive study is done in order to estimate how x_s~{max} is influenced by the B-decay proper-time resolution of the vertex detector, as well as by the number of events and by the signal-to-background ratio.
