Field emission studies on technical niobium surfaces
Description
The performance of superconducting accelerating cavities are limited by the spurious field emission of electrons. Various vacuum surface treatments have been investigated in a UHV system to reduce the emission. On baked niobium samples, the application of an electrical field leads to a gradual decrease of the field emitted currents; after an argon glow discharge, the currents are high and stable. An argon/oxygen discharge reduces markedly the field emitted currents
