摘要
在HI-13串列加速器上建立了我国第一台氚气体靶装置.氚气体靶采用双窗结构,入射窗为Mo箔.Mo窗把气室分成氚气室和氦气室二部分.实际运行时,氚气室的氚气压力为2×105Pa,氦气室的氦气压力为3×104Pa.氚气体靶装置在入射氘束流能量为20MeV、流强1.5μA时,可长时间安全运行,已应用于中子物理的实验测量工作.
A tritium gas target has been built and employed in neutron physics experiments at HI-13 tandem accelerator. The gas target consists of a helium gas cell and a tritium gas cell. The entrance foils are 10 μm thick molybdenumones ones. The target is intended as a neutron source using T(d,n) 4He and T(p,n) 3He reactions. Details of the target design and performance are given.
