Carbon cluster beam of MeV C_2-C_4 has been successfully accelerated on HI-13 tandem accelerator,researches of interaction between these particles and plastic track detector CR-39 has been lead out. Sincethe mass energy product of analysis magnet on HI-13 tandem accelerator is 200 MeV·Amu, only lowenergy C_2-C_4 cluster beam could be deflected and analyzed in the experimental hall. In order to obtainhigher energy C_2-C_4 or bigger clusters as well as other types of clusters (such as Si_n and Au_n, etc.), a beam
