Cyclotron optimization starting method based on continuous closed-loop mode

The invention discloses a cyclotron optimization starting method based on a continuous closed-loop mode, and the method comprises the steps: carrying out the initialization preparation work, entering a low-power tuning state in the continuous closed-loop mode, and achieving the tuning closed-loop in the low-power state; entering a pulse search state in a continuous closed-loop mode and realizing a tuning closed loop in the pulse search state; entering a power boosting state in a continuous closed-loop mode and realizing an amplitude closed loop in the power boosting state; and entering a normal operation state in a continuous closed-loop mode and realizing cavity pressure balance in the normal operation state. According to the invention, the quality factor of the cavity is improved through the pre-tuning point; and a pre-tuning mode is adopted before the two stages of improving the power. When the pulse searching state is entered and the power is improved, the input power of the cavity is the maximum, and the
