This work represents a new approach for analyzing emission characteristics of multitip field cathodes. The approach is based on using a computerized field emission projector to investigate the behavior of the microscopic emission sites of the field cathode surface. Adsorption-desorption processes on the surface—which influence the emission current level—were investigated by tracking the individual emission sites under conditions of a sharp decrease and increase in the voltage level. An analysis of the transient process showed that emission sites with highest local currents almost do not participate in changing the overall level of emission current, but they became smaller with a decrease in the step voltage contribution of the dimmest sites. Similar dependences were obtained for rising voltage levels but with much faster transitions.

用计算机化场发射投影仪研究多尖端场发射器的电流电平不稳定性

这项工作代表了一种分析多尖端场阴极发射特性的新方法。该方法基于使用计算机化的场发射投影仪来研究场阴极表面的微观发射位点的行为。通过在电压水平急剧下降和增加的条件下跟踪单个发射位点，研究了表面上的吸附-解吸过程（影响发射电流水平）。对瞬态过程的分析表明，具有最高局部电流的发射点几乎不参与改变发射电流的整体水平，但随着最暗点的阶跃电压贡献的降低，它们变得更小。对于上升的电压电平获得了类似的相关性，但转换速度要快得多。
