Performance of MgO/Au cermet films as secondary electron emission cold cathodes

The performance of MgO/Au cermet films as secondary electron emission cold cathodes was tested in a crossed‐field amplifier (CFA) tube until it showed signs of cathode insufficiency. Only 5–25% of the original cermet thickness (4000 Å) was left. Although heavy C coverage was observed, which degraded...
