摘　　要：本文描述MM-4U装置及其初步实验结果。这些结果主要是,用电子注入可以在装置系统中建立等离子体;测得轴向等离子体电位分布,东、西会切中心和中心室的等离子体电位分别为-184V,-164V和-1.8V;得到轴向电子密度分布与电位分布有相同形式,三个中心的密度分别为1.7×10^(11)cm_(-3),4.7×10^(10)cm^(-3),7.5×10~7cm^(-3);观测到中心室存在不稳定性,其振荡频率为7—9.2kHz。对上述结果进行了分析,提出了进一步研究的课题。The MM-4U device is briefly described and the preliminary experiment results are presented.The plasma has been produced by injecting a strong electron beam.The axial profiles of the plasma potential and the plasma electron density were obtained and they have a similar form.The plasma potentials in the centre of the oast and west cusp and the contre cell are Fe=l84V,Vw=-164V and Vc=-1.8V with electron density ne=1.7×1011cm-3,nW=4.7×1010cm-3 and nc=7.5×107cm-3 respectively.Some plasma instability phenomena have been observed in the centre cell.Its oscillation frequency is in the range of 7-9kHz.The program for the future physical experiment is given.
