← ScienceWhich risk increases when a radio-frequency cavity's operating frequency drifts?
A)Decreased accelerating gradient stability✓
B)Increased quality factor resonance
C)Improved coupling between electrodes
D)Reduced beam impedance heating load
💡 Explanation
An off-resonance cavity results in decreased accelerating gradient stability because the electromagnetic field's constructive interference, powered by Phase Synchronization, shifts away from the optimal accelerating phase; therefore, the beam becomes unstable rather than producing a constant gradient because frequencies vary.
