Kimball Yttria Coated Iridium Disc Cathodes 氧化钇阴极
Kimball Yttria Coated Iridium Disc Cathodes 氧化钇阴极
Description
Kimball Physics offers a Yttria Coated Iridium Disc Cathode. In addition to being a ruggedized thermionic emitter that resists oxidation, these cathodes provide stable and uniform electron emission for a wide variety of electron source applications, especially where vacuum conditions are not ideal. The cathode structure of the ES-535, ES-526, and ES-529 consists of a yttrium oxide coated iridium disc that is heated by conduction from an iridium hairpin and mounted on an AEI or a Kimball Physics base. The ES-535W consists of a yttrium oxide coated iridium disc with tungsten hairpin in place of the iridium hairpin. Other bases are available on a custom basis. Kimball Physics提供钇涂层铱盘阴极。除了是一种抗氧化的加固热离子发射器外，这些阴极还为各种电子源应用提供了稳定和均匀的电子发射，尤其是在真空条件不理想的情况下。ES-535、ES-526和ES-529的阴极结构由氧化钇涂覆的铱盘组成，该铱盘通过铱发夹的传导而加热，并安装在AEI或Kimball Physics基座上。ES-535W由一个氧化钇涂层铱盘组成，用钨发夹代替铱发夹。其他基地也可定制。- Chemically resistant
