Abstract
Official abstract text for this publication.
There is provided a liquid metal target forming apparatus, including a nozzle that forms a liquid metal target in space, which is irradiated with a proton beam, by ejecting liquid metal thereto. A portion where a region that receives a proton beam of the liquid metal target is formed in a discharge port of the nozzle has a concavo-convex shape.
First claim
Opening claim text (preview).
The invention claimed is: 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. 2. The neutron generator according to claim 1 , wherein a minute wave is generated on a free liquid level of the concavo-convex shaped wave surface, and a difference in height of the concavo-convex shape of the discharge port of the nozzle is greater than a wave height of the minute wave. 3. The neutron generator according to claim 1 , wherein the concavo-convex shape of the discharge port is a concavo-convex shape which generates a standing wave or a ship wave in a region that receives the proton beam of the liquid metal target formed by ejecting liquid metal. 4. The neutron generator according to claim 1 , wherein the concavo-convex shape is a waveform, a comb shape, or a serration. 5. The neutron generator according to claim 1 , further comprising: a quench tank connected to the nozzle and the receiving portion, and a pump connected to the quench tank; wherein the nozzle, the receiving portion, the quench tank and the pump form a liquid metal loop in which the liquid metal circulates. 6. The neutron generator according to claim 1 , wherein an ejection velocity of the liquid metal is equal or more than 3.0 m/s and equal to or less than 20 m/s. 7. The neutron generator according to claim 6 , wherein the nozzle ejects the liquid metal with disturbed flow.
