高功率太赫兹光谱中高频回旋管输出功率的高稳定性是将回旋管应用于更广泛领域的一个重要问题。为此，我们尝试对三极管磁控管注射枪（MIG）的加热器电流进行PID反馈控制，以稳定电子束电流，并对枪的阳极电压进行额外PID控制，以直接稳定输出功率。这种双PID控制在缓慢（从几十秒到几分钟）和快速（从毫秒到秒）时间尺度上实现了输出功率稳定的有效响应。
High stabilization of the output power of high frequency gyrotrons for high power THz spectroscopy is an important issue in order to extend the applications of gyrotrons to wider subjects. For this objective, we tried a PID feedback control on a heater current of a triode magnetron injection gun (MIG) for stabilization of an electron beam current and an additional PID control of an anode voltage of the gun for direct stabilization of output power. This double PID control achieved effective responses for the stabilization of output power in both slow (from several tens seconds to several minutes) and fast (from milliseconds to seconds) time scales.
