利用计算机模拟研究了电子回旋自共振脉塞（CARM）放大器通过磁场变细提高效率的方法。根据初始频率不匹配，用负或正梯度逐渐减小磁场可以提高效率，而不是谐振调谐CARM。然而，锥形对进一步提高最佳失谐装置的效率几乎没有影响。当力聚束在聚束过程中起重要作用时，锥形也变得无效。对这些发现提出了物理解释。
Efficiency enhancement in an electron cyclotron autoresonance maser (CARM) amplifier through magnetic field tapering is investigated using computer simulations. Depending on the initial frequency mismatch, tapering the magnetic field with either a negative or positive gradient can enhance the efficiency over that of the resonantly tuned CARM. Tapering, however, has little effect in further increasing the efficiency of the optimally detuned device. Tapering also becomes ineffective when force bunching plays a significant role in the bunching process. A physical explanation for these findings is presented.
