In the CERN PS Booster, wire-scanner profile measurements performed at injection energy are affected by a strong asymmetry. The shape was reproduced with the code pyOrbit, assuming that the effect is due to the beam evolution during the scans, under the influence of space-charge forces and Multiple Coulomb Scattering at the wire itself. Reproducing the transverse profiles during beam evolution allows to use them reliably as input for simulation benchmarking.

Transverse emittance is one of the key measurements to be performed during the commissioning of the low energy sections of an hadron linac. The good knowledge of the beam transverse phase space allows a safe and efficient operation of the machines by using the results of the measurement for beam dynamic simulations. In this paper we will discuss the accuracy and the limits of the transverse emittance measurement performed with the slit-grid method based on the ESS beam parameters at the RFQ (beam energy equal to 3.62 MeV) and DTL tank 1 (beam energy equal to 21 MeV) output.
