The distribution of ion beam density extracted from a MEVVA ion source is studied by three methods. The first is using a cusped magnetic field; the second is increasing the distance between the cathode and the anode of the MEVVA source and confining the emitting angle of the plasma so that the potential of the anode is higher than that of the plasma; the third is changing the anode structure of the MEVVA ion source so as to change the route of the vacuum are.Experimental results suggest that the third approach...

通过采用加会切磁场、增大离子源阴极与阳极距离并限制源等离子体发射角,从而使源阳极电位高于等离子体电位和采用改变源阳极结构──仅用阳极筒──从而改变弧放电路径这3种方法,对改善MEVVA源引出离子束流密度分布的均匀性进行了初步的研究。第3种方法从根本上改变了MEVVA源引出束分布的高斯分布特性,在合适的条件下可能得到更为均匀的束流密度分布。

A new preliminary design programme for plasma-assisted chemical vapour deposition(PVCD) furnace due to inltomogeneity of electric field and reaction gases inthe existing furnace is presented. The key of this design is that in the vaccumchamber of the furnace,anode bucket and gas tube with holes on it can be drived to spin by motor through transmission mechanism.

根据当前等离子体化学气相沉积(PVCD)炉所存在的电场及供气分布不均等问题,提出了一种新的设计方案。其特征在于真空室内的阳极筒由控制电机通过传动机构带动旋转,反应气体通过旋转的气流分配系统导入真空室;本设计的预期效果是在进行PCVD处理时,通过旋转校正阳极筒椭圆度和工作时自身变形所造成的电场分布不均,并能使反应气体在工件大面积内达到均匀分布,以提高表面沉积层的厚度一致性及其致密性。

A novel temperature difference technique,which considerably reduces alkali vapor contamination,has been successfully deve- loped in fabricating the multi alkali cathodes of the 20/30 invert image intensifier tube.In cathode fabrication,a temperature controllable oven is introduced to raise the temperature of the bottom part of the tube,which contains the screen and the microchannel plate (MCP),100 ℃ higher than the front part.The MCP sample was studied with X-ray photoelectron spectroscopy (XPS).XPS results show that the alkali vapor contamination has been significantly reduced,The concentrations of Na,K,and Cs are 3.07%,2.23% and 0.00%,respectively,whereas for the control sample,fabricated in conventional technique,the concentrations of Na,K,and Cs are 6.32%,2.70% and 0.36%,respectively.

所谓温差法就是在制备 2 0 / 30倒像管多碱阴极过程中 ,将像管后半部分套一可控温小电炉 ,使荧光屏和微通道板(MCP)等部位的温度始终比阴极基底高 10 0℃左右 ;阴极制备结束后 ,取下管内的MCP进行XPS分析 ,同时还与用标准工艺制备阴极后取下的MCP进行对比分析。XPS谱图表明 ,前者检测到的Na为 3 0 7% ,K为 2 2 3% ,Cs为 0 0 0 % ;后者检测到的Na为 6 32 % ,K为 2 70 % ,Cs为 0 36 %。实验说明 ,在制备阴极过程中 ,阳极筒和荧光屏端温度高于阴极面激活温度 ,使得吸附在MCP电极表面以及阳极筒等高温部件的碱金属 ,尤其是Na的含量降低。从而说明温差法是降低碱金属蒸气对像管内其它部件的污染 ,改善背景噪声的有效方法之一。
