For the SPARC photoinjector commissioning the emittance compensation process has been studied experimentally under different beam conditions (variation of charge, spot size, beam shape....) by a novel device called “emittance-meter”, consisting in a movable emittance measurement system based on the 1D pepper pot method scanning a region 1.2 m long downstream the RF-gun. The results of a detailed comparison between the measurements and beam dynamics simulations performed by the codes (PARMELA,HOMDYN,TREDI) employed for SPARC design are presented and discussed here
