摘要

P 1. Method for analyzing primary neutron radiation of a neutron source, a neutron source provided with a beam controller and a beam controller.2.1 The known beam controllers are fission chambers which are arranged in the primary neutron beam. Free charge carriers are generated in the fission chambers during fission processes triggered by the neutrons, said charge carriers producing an ionization pulse that can count the neutron when the voltage is applied. During fission, unwanted fast neutrons and high energy gamma radiation are created as by-products. The slow neutron flux can be further weakened by the gas filling the fission chambers. These disadvantages can be avoided with the new process, the new neutron source and the new beam controller.2.2 Neutrons are scattered incoherently out of the primary neutron radiation (1) by means of a diffusion film (4). Part of the scattered neutrons (5) meet a detector device (6) which is arranged outside the primary neutron radiation (1). The beam controller (2) can very well be configured to be able to determine the spatial distribution of neutrons in the primary neutron radiation (1) as well as the spectral distribution in the case of pulsed neutron sources.2.3 Radiation analysis primary neutron of a neutron source, including a pulsed spallation neutron source. / P

1.一种分析中子源的初级中子辐射的方法，一种配备有束控制器的中子源和束控制器。2.1已知的束控制器是布置在初级中子束中的裂变室。在由中子触发的裂变过程中，在裂变室中生成自由电荷载流子，所述电荷载流子产生电离脉冲，当施加电压时，该电离脉冲可以对中子计数。在裂变期间，副产物会产生不需要的快速中子和高能伽马射线。缓慢的中子通量可通过充满裂变室的气体进一步减弱。这些缺点可以通过新的工艺，新的中子源和新的射束控制器来避免。2.2中子通过扩散膜（4）从初级中子辐射（1）中非相干地散射。散射中子（5）的一部分与探测器装置（6）相遇，探测器装置（6）布置在初级中子辐射（1）的外部。波束控制器（2）可以很好地配置为能够确定初级中子辐射（1）中的中子的空间分布以及脉冲中子源情况下的光谱分布.2.3辐射分析中子的初级中子中子源，包括脉冲散裂中子源。展开▼
