中子发生器靶的寿命是使用中一个较突出的问题。为提高靶的寿命,一般采用各种形式的旋转靶。本文介绍采用磁场扫描方法使束斑在靶的活性区做圆周运动,使束的功率密度不致太集中于某个区域,从而改善了靶的冷却,使钛氚靶在10
10
n/s产额下半寿命比原来提高了3~4倍。如配合使用旋转靶,将使靶的寿命进一步提高。
A simple device for increasing neutron target life-time is described. Two sets of magnetic poles excited by the phase quadrature 90°
50Hz power supplies were used to scan the ion beam. The Ti-T target half life-time can be increased by a factor of 4~5.
