Introduction The study of the deuteron-proton elastic scattering has a longtime story. The first nucleon-deuteron ex- periments were performed already in the 1950’s [1-7]. Differential cross-section and nucleon analyzing pow- ers [5-7] were measured at few hundred MeV. Nowa- days this reaction is still the subject of the investigations [8-10]. The purpose of DSS (Deuteron Spin Structure) project is the broadening of the energy and angular ranges of measurement of different observables in pro- cesses including 3-nucleon systems. The main aim of the offered experiment program is the extraction of the information on the spin dependent part of 3-nucleon forces. DSS project experimental program includes 2 experiments, one of them is the experiment on dp- elastic scattering study. It includes measurement of cross-section, vector A y , tensor A yy and A xx analyzing powers in dp-elastic scattering in the range of 300 and 2000 MeV of the deuteron kinetic energy. The goal of present investigation is to measure the cross-section of dp-elastic scattering at 400-880 MeV using the kinematic coincidences of deuteron and pro- ton with plastic scintillation counters. Measurements were performed using polyethylene and carbon targets. The selection procedure is based on the CH 2 -C ampli- tude spectra subtraction.
