Abstract: The present invention provides a neutron generating device for generating a high neutron flux by forming plasma in the vicinity of a target and by accelerating electrons and charged particles in the plasma toward the target. Magnetic field is formed in the vicinity of the target and a microwave generator irradiates microwaves into the space where the magnetic field is generated to thereby generate plasma in the space. The accelerated electrons and charged particles collide with the target to generate neutron flux. Also, to prevent the target surface from being excessively heated, the plasma is generated in a pulsed mode and target voltage is applied in a pulsed mode. To secure a continuous process, the level of target bias voltage for the target is adjusted so that the target re-adsorbs elements when the elements adsorbed on the target are depleted.
