The present invention relates to a device for generating a pulse by passing proton beams through a slit. The device comprises: an ion source for generating proton beams linearly moving in one direction; a biased unit provided to be spaced apart from the ion source, disposed in a linear pathway of the proton beams, applying a voltage, and formed to bend the proton beams in one side; and a slit unit provided to be spaced apart from the biased unit in the progress direction of the proton beams, and forming a slit through which the proton beams may pass, in a step of bending the proton beams in another side by changing a voltage of the biased unit. The slit unit is formed to be able to adjust a size of the slit, so the width of a pulse which is time in which the proton beams pass through the slit may be controlled while the progress direction of the proton beams is changed by means of a change in the voltage. |
