In LHC it will be important to measure with precision and in a non‐destructive way the proton beam profiles from 450 GeV to 7 TeV. The chosen monitor will make use of a 5 T superconducting Undulator with two periods coupled to the D3 bending magnet built by BNL. From the various variants studied, this combination is the only one which could cover the whole LHC energy range. By locating both magnets in the same cryostat, it will be possible to minimise the light source length for best precision. The choice of the undulator parameters and its basic design will be described. The evolution of the synchrotron radiation patterns along the energy ramp will be given, as well as the performance with respect to sensitivity, depth of field and diffraction, with a description of the simulation codes used.
