Claim:
1. A neutron generator, comprising an accelerator that irradiates with a proton beam, a nozzle that forms a liquid metal target in space, which is irradiated with the proton beam, by ejecting liquid metal thereto, a receiving portion that faces the nozzle, the receiving portion receives the liquid metal target from the nozzle, a portion which forms a part of a region in a discharge port of the nozzle has an elongated shape wherein at least one long side of the discharge port of the nozzle has a cyclical concavo-convex shape; wherein generating neutrons by receiving the proton beam between the nozzle and the receiving portion at least in the part of the region where the liquid metal target is formed, the nozzle ejects the liquid metal target to the receiving portion linearly, and wherein a wave surface of the liquid metal target forms a concavo-convex shape corresponding to the concavo-convex shape of the discharge port of the nozzle, and the liquid metal is liquid lithium.
