The potential for two-particles correlation studies is investigated using data collected by the HERA-B experiment. HERA-B is a fixed-target multi-particle spectrometer experiment operating at the 920 GeV HERA proton beam at DESY. The minimum bias data sample from the 2002/2003 HERA run, consisting of 200 million interactions recorded with a minimum bias trigger, provides the opportunity of determining the Bose--Einstein correlation function parameters for both pion and kaon pairs. Preliminary results, for pions, are presented.
