Abstract
The efficiency dependence of a cyclotron autoresonance maser (CARM) amplifier on electron beam current and input power is investigated using computer simulations and a theoretical model is presented to explain the findings. For a resonantly tuned CARM, the efficiency is found to initially increase and then decrease with beam current while for an optimally detuned CARM, the efficiency drops with any increase in beam current. If the current is kept constant, the efficiency is also found to drop as the input wave power is increased. Force bunching is found to play an important role in reducing the efficiency at high-beam current, which may make extension to high power through increasing beam current more difficult to achieve.
