	The European Spallation Source (ESS), currently under construction, consists of a partly superconducting linac which will deliver a 2 GeV, 5MW proton beam to a rotating tungsten target. Beam transverse profile monitors are required in order to insure that the lattice parameters are set and the beam emittance is matched. Due to the high intensity of the beam and the constraint to perform non-disturbing measurements, non-invasive techniques have to be developed. The non-invasive profile monitors chosen for the ESS are based on the interaction of the beam with the residual gas. Two different devices are developed, one utilises the fluorescence process, the other one the ionisation process. The paper presents their latest preliminary developments.

The pick-up geometry is simulated to estimate its sensitivity towards the beam dipole and quadrupole moments.
