Which risk increases when a high-power microwave tube rapidly cycles through power states?

💡 Explanation

Rapid power cycling elevates localized spots, causing thermionic emission—a form of space charge limitation—because electron emission increases exponentially with temperature, therefore leading to arcing rather than gradual sublimation found in constant operation or superconducting effects in unrelated systems.
