摘　　要：With the development of radioactive beam facilities,several exciting results were provided concerning the understanding of fundamental nuclear physics.However,typical-beam intensities are always low and the production is often in very small quantities,so,new generation detectors need to be developed with large solid angle and angular coverage,which can identify particle effectively as well as possesses high energy resolution,high spatial resolution and high geometric efficiency.The new detector based on Double Side Silicon Strip Detector(DSSD)is foreseen for the study of the reaction production in the experiment of direct nuclear reaction above the Coulomb barrier using RIBLL[1,2]at the HIRFL[3,4].However,the disadvantage of the RIBs is that it has a broad distribution in coordinate spaces.Therefore,new detector system with high resolution and a large solid angle was developed successfully for performing nuclear reaction experiments using RIBs.The geometric efficiency of the new detector array with 5 large area DSSD telescopes increases up to 70%.
