500仟伏以下的高压倍加器,大部分用作为快中子源,产生单能的快中子,产生的方法是利用氢的同位素——氘或氚作为离子束轰打氘或氚核,引起核反应产生具有2.5—1.6兆电子伏能量的中子,但作为制备氚离子源的原料——超重氢,不易获得;而作为制备氘离子源的原料——重氢却容易得到。因此,在一般情况下,采用氘离子束轰打原子核较为实际,通过核反应所产生的中子,可以用来进行有关快中子方面的研究工作或生产短寿命的放射性同位素。本文将具体介绍一种用电解槽电解重水产生氘离子的装置。
High-voltage multipliers, up to 500 kV, are mostly used as fast neutron sources to generate single-energy fast neutrons by generating hydrogen isotopes of deuterium or tritium as ion beams that strike deuterium or triton, causing Nuclear reactions produce neutrons with 2.5-1.6 MeV energies, but are not readily available as raw materials for the preparation of tritium sources - over-weight hydrogen; however, deuteration is readily available as a starting material for the deuterium ion source. Therefore, it is generally practicable to bombard nuclei with a deuterium ion beam. The neutrons generated by the nuclear reaction can be used to carry out research on fast neutrons or to produce short-lived radioisotopes. This article will specifically introduce a device for electrolysis of heavy water to produce deuterium ions.
