Emittance scans comparison with LHC wire scanner

High-luminosity production at the LHC is closely linked to the size of the transverse beam emittance. However emittance measurement is challenging. It is important to use multiple methods for emittance measurement to gain confidence in the absolute value measured and to improve our knowledge of emittance evolution during ``stable beams'' conditions. In the proceedings to Lumi days, the potential of emittance scans for emittance measurement is studied. Comparison between the emittance measured using emittance scans at CMS in the noncrossing plane and wire scanners is presented.
