摘要
为了可能在微型扫描电子显微镜中使用，测量了三极管结构中浸渍阴极的亮度和能量扩散。标准化亮度为2.104 a /sr.m2。我们测量到的能量扩散是0.8 ev。
Brightness and energy spread measurements for an I-cathode
For possible use in a miniature scanning electron microscope, the brightness and energy spread of an impregnated cathode in triode configuration were measured. For a normalized brightness of 2.104 A/sr.m2.V we measured an energy spread of 0.8 e V.
