Summary:A novel neutron tube arc detection circuit comprises a current transformer, a bridge rectifier circuit, an RC low-pass filter circuit, a hysteresis comparator, an arc amplitude setting circuit and an optocoupler circuit. An arc signal is converted into a voltage signal through the current transformer and the bridge rectifier, and the arc voltage signal is filtered through the low-pass filter, so that the anti-interference capability of the arc detection circuit is improved. And the arc voltage signal is compared by the hysteresis comparator, so that error output caused by signal disturbance can be further removed, and the anti-interference capability is improved. Meanwhile, the comparison voltage of the hysteresis comparator is adjustable, the flexibility of the circuit is improved, and small electric arcs can be ignored. The arc detection circuit has the advantages of strong anti-interference capability and high detection precision, is especially suitable for being used in a neutron tube accelerating pole po
