1. 前言最近,核聚变堆的研究在采用氘-氚反应的第二代反应堆的基础上已有所发展。这种反应是氘原子核与氘原子核的反应,它生成了具有3.5兆电子伏能量的氦原子核(α粒子)与具有14.1兆电子伏能量的中子(n)。理想情况是把3.5兆电子伏的能量全都用来加热等离子体,但实际上一部分α粒子会从等离子体中逸出并轰击第一壁。具有一定能量的α粒子在注入第
1. INTRODUCTION Recently, the study of fusion has evolved based on the second generation of reactors using deuterium-tritium reactions. This reaction is the reaction of the deuterium nucleus with the deuterium nucleus, which generates a helium nucleus (alpha particle) with 3.5 mega-electron energies and a neutron (n) with 14.1 mega-electron volts energy. Ideally, 3.5 megawatts of energy is used to heat the plasma, but in reality a portion of the alpha particles will escape from the plasma and strike the first wall. Alpha particles with a certain energy are injected into the first
