小型密封式中子发生器中子通量密度的水平方向分布

Neutron Flux Density of Horizental Direction Distribution for Sealed Small-Sized Neutron Generator

对小型密封式中子发生器进行了水平方向中子通量密度分布的测定。近靶处中子通量密度分布梯度较大，远靶处近似呈反平方规律分布。

The neutron flux density of horizental direction distribution for sealed smallsized neutron generator is measured.The results show that the distribution gradient of the neutron fulx density is large in the near target and is anti-square in the far target.
