Kimball Barium Oxide Coated Disc Cathodes 氧化钡阴极
Description
The Kimball Physics Barium Oxide Coated Disc Cathode is a low-light, low-temperature thermionic emitter. The cathode structure of the ES-015, ES-064, and ES-066 consists of a barium oxide (BaO) coated disc substrate that is heated by conduction from a tungsten hairpin and mounted on an industry-standard ceramic AEI base or on a compact Kimball Physics ceramic base. Other bases are available on a custom basis.
- Low light, low temperature
- Emission current densities up to 0.25 A/cm2
- Operating pressure < 10-7 torr
- Emission up to 3 mA
- 3 disc sizes
- On AEI or compact CB-104/105 bases
