| 摘 要： | 报道了六硼化镧（LaB6）场发射尖锥的场发射性能。采用电化学腐蚀方法制作了LaB6场发射尖锥，并在10-2～10-7 Pa 的宽真空度范围内对单尖LaB6场发射二极管的发射特性进行了测试。发现残余气体电离产生的离子轰击对LaB6场发射阴极尖锥表面起到了离子清洗作用，使LaB6场发射尖锥在低真空工作后发射电流大幅度提高。离子轰击是一种适用于LaB6场发射阴极的激活处理方法。

| Abstract: | The influence of the channel parameters of the water-cooled Si mirror on temperature and thermal deformation was simulated using ANSYS finite element analysis. The results show that the channel parameters have significant effects on the thermal deformation. For a given flow rate of water, the temperature rise and thermal deformation decrease with the decreasing of channel width. With a constant flow rate and channel width, the thermal deformation decreases with the channel depth. However, the effect of channel depth on temperature rise is not obvious. For the water-cooled mirror, it would be better to make the channel small. For high power laser, the channel size of the water-cooled mirror is several hundred mm to 1 mm. |
