Part 6/10:
- Scaling to Higher Frequencies: To achieve even higher resonant frequencies, multiple loops or resonators with reduced dimensions are used, often arranged in parallel to minimize inductance and maximize the frequency.
Electron Dynamics and Signal Modulation
The interaction between the electron beam and the cavity fields results in current modulation:
- Electron Acceleration and Deceleration: The alternating electric field causes electrons to gain or lose energy. Since the electrons are negatively charged, they are accelerated against the electric field and decelerated along it, resulting in velocity variations.
