Oneof the main goals is to determine the substructure of the proton with the best pos-sible precision. This is done measuring the inclusive deep-inelastic scattering cross2section as a function of the kinematic variables Q and x.This work presents a new measurement of the inclusive deep-inelastic electron-proton scattering cross section using the data taken with the H1 experiment in theyear 2000. The measurement is restricted to the region of low and intermediateinelasticities y, where the background is low. In this domain the reduced crosssection is mostly identical to the proton structure function F .
