摘要

与热离子阴极相比，更高的发射密度、更快的开关、更低的功耗和更低的热负荷只是基于场发射(FE)的电子源提供的优势中的一小部分。一旦电磁场发射阵列(FEA)的制造工艺成功，许多应用都等待着作为电子枪的电磁场发射阵列(FEA)建立简单可靠的方法来比较和评估不同类型的电磁场发射阵列。本文提出了一种简易的有限元分析制作方案和通用性能测试方法。

Inhalt: Vakuum in Forschung und Praxis 3/2023

The “LED-version” of the electron gun An electron source for operation in ambient pressure environments based on silicon field emitter arrays M. Bachmann, F. Düsberg, A. Pahlke, S. Edler, A. Schels, F. Herdl, M. Hausladen, P. Buchner, and R. Schreiner Higher emission density, faster switching, lower power consumption and a reduced thermal load are only a few of the advantages that field emission (FE) based electron sources offer compared to thermionic cathodes. Many applications await field emitter arrays (FEA) acting as electron guns, once their manufacturing process succeeds simply and reliable methods for comparability and evaluation of different field emitter types are established. An easy fabrication scheme for FEAs and an universal performance test are presented here.
