Abstract	LINAC4 is a new linear accelerator for H- ion which will replace proton Linac2 as injector for the CERN proton accelerator complex. LINAC4 accelerates H− ions from 45 keV to 160 MeV in a sequence of normal conducting structures. Then, H- ions with a kinetic energy of 160 MeV will be sent to the PS Booster. This note describes two energy measurement methods and a improved method that will be used for longitudinal emittance reconstruction with space charge by multi-particle tracking code and the expected results.
