Transverse Emittance reconstruction in presence of space charge and application to the 50 MeV beam of Linac4

During the commissioning stage of Linac4 a test bench is planned to be used in order to characterize the 50 MeV beam after the DTL. Among other parameters, it will be possible to measure the transverse emittance using both the 3 monitors and the quadrupole scan method. As the space charge effects are not negligible at this energy, classical techniques of emittance reconstruction become questionable and a different approach based on recursive beam dynamics simulations must be applied.
