Abstract：
Beijing intense slow positron beam has been constructed successfully, which utilizes the pulsed electron beam of the BEPC LINAC with high energy to inject into the Ta target. The system will be used to expand the methodology research on positron beam and to study the defect of film materials. The running performance of DC positron beam will be introduced in this paper, such as the intensity, the energy spread and the beam size. As the main measurement method, Doppler broadening spectrum system of positron annihilation has also been accomplished.
