摘　　要：将在分析束(D_1^-)轰击下,大面积高速旋转靶半寿命、中子比产额等指标与非分析束作了比较。中子比产额从1.1×10^(11)s^(-1)·mA^(-1)提高到1.6×10^(11)s^(-1)·mA^(-1),氚钛靶半寿命提高一个数量级,靶寿期由1mA·h/cm^2提高到6.9 mA·h/cm^2。The neutron yield and lifetime of T-Ti rotating target bombarded by analyzed deuterium beam aredescribed and compared with that for nonanalyzed beam. The neutron yield is increased from 1.1×10^(11)s^(-1)·mA^(-1) to 1.6×10^(11)s^(-1)·mA^(-1), lifetime of T--Ti target is increased from 1 mA·h/cm^2 to6.9 mA·h/cm^2 after improvement of the accelerator.
