摘要

超冷中子源的概念是基于极冷中子(VCNs)在局部减速装置中的减速。后者被认为是一个梯度自旋鳍。结果表明，在这种情况下，减速后转化为ucn的vcn的通量具有脉冲结构，中子束的持续时间明显短于它们的重复周期。因此，束中的中子通量密度明显超过平均值。这开辟了脉冲填充UCN阱的可能性，而不需要预先的时间聚焦。

On a New Possibility of Pulsed Accumulation of Ultra Cold Neutrons in a Trap

The concept of an ultracold neutron (UCN) source is considered based on the deceleration of very cold neutrons (VCNs) by a local decelerating device. The latter is proposed to be a gradient spin flipper. It is shown that, in this case, the flux of VCNs, which are converted to UCNs after deceleration, has a pulsed structure, and the duration of neutron bunches can be significantly shorter than their repetition period. Accordingly, the density of the neutron flux in the bunch significantly exceeds the average value. This opens up the possibility of the pulsed filling of the UCN trap without preliminary time focusing.
