| 词条 | Hollow cathode effect |
| 释义 |
The hollow cathode effect allows electrical conduction at a lower voltage or with more current in a cold-cathode gas-discharge lamp when the cathode is a conductive tube open at one end than a similar lamp with a flat cathode.[1] The hollow cathode effect was recognized by Friedrich Paschen in 1916.[2] In a hollow cathode, the electron emitting surface is in the inside of the tube. Several processes contribute to enhanced performance of a hollow cathode:
The hollow cathode effect is utilized in the electrodes for neon signs, in hollow-cathode lamps, and more. References1. ^1 {{cite journal|last1=Eichhorn|first1=H.|last2=Schoenbach|first2=K.
