It is composed of 14 and 15 and anvils 9 and 10. The bore component 6 comprises a pair of conductive rails 5 and a pair of insulating rails 4b, and the conductive rails 5 are separated by the insulating rails 4b so as not to short-circuit with each other. Also,
An insulating material 7b and an insulating material 8 are inserted between the conductive rail 5 and the outer anvils 9 and 10 to prevent the pair of conductive rails 5 from being short-circuited through the outer anvils 9 and 10.

That is, as shown in FIG. 8, the sum of the force F 2 and the electromagnetic force F 1 by high pressure plasma phase repelled a pair of conductive rails 5, the force F 2 is acting by high pressure plasma in a pair of insulating rails 4b To do.

に加速されない。Due to the electromagnetic force F 1 and the force F 2 generated by the high-pressure plasma, the contact surface pressure P 2 on the contact surface between the insulating rail 4b and the conductive rail 5 decreases, so that the insulating rail 4b
The force that restrains the area around is reduced. Since the rigidity of the insulating rail 4b is much smaller than that of metal when the restraining force becomes smaller, the insulating rail 4b is largely compressed and deformed by the force F 2 due to the high-pressure plasma acting on the insulating rail 4b, and the inner diameter of the insulating rail 4b is reduced. It becomes large and a gap is created between the projectile and the projectile, and high-pressure plasma that accelerates the projectile leaks from this gap (escapes in front of the projectile), and the projectile is not effectively accelerated.

That is, the acceleration efficiency is reduced.

め、金属と異なり、通電時の渦電流損失も生じない。[Function] The rigidity of the insulating rail and the insulating material is improved by processing the insulating rail and the insulating material with a non-conductive material such as high-rigidity ceramic as a core material and processing the core material from an insulating material coated with the non-conductive material. Is larger than that processed from a conventional rod-shaped polymer insulating material such as polycarbonate or FRP. That is, the rigidity such as ceramics is much larger than that of the non-conductive polymer material, and the amount of compressive deformation of the insulating rail and the insulating material is almost proportional to the length of the polymer material, so the core material is covered. By reducing the thickness of the polymer material used, the rigidity of the insulating rail and the insulating material can be increased, and the amount of compressive deformation can be reduced to such an extent that it can be almost eliminated. Therefore, even when the conductive rail is energized, the gap between the insulating rail and the conductive rail backed up by the insulating material and the projectile becomes small, and it is possible to prevent leakage of high-pressure plasma that accelerates the projectile. The acceleration efficiency of the body can be increased.
In addition, since the core material such as ceramics is a non-conductive material, eddy current loss during energization does not occur unlike metal.

レン（ＦＥＰ）などのテフロン系が好ましい。In the case of a long insulating material, if the core material becomes too long and easily breaks, the core material divided in the length direction is arranged in one core material, and the core material is heat-shrinked. By fixing with a tube and using it as a core material, a long core material can be obtained. A glass fiber is wound around the outer surface of the core material and hardened with an epoxy resin to cover the core material to form a long insulating material. Similarly, a long core material can be obtained by stacking core materials such as highly flexible thin plate-shaped ceramics while shifting them from each other and fixing them with a heat-shrinkable tube to form a core material. The heat-shrinkable tube is preferably made of Teflon such as fluoroethylene propylene (FEP) from the viewpoint of heat resistance and rigidity.

An insulating material may be used by press-fitting or shrink-fitting a core material divided in the length direction into an FRP cylinder manufactured by hardening with an epoxy resin. This makes it possible to obtain a long insulating material without using a heat shrinkable tube. The cross-sectional shape of the core material such as ceramics coated with the non-conductive material used for the insulating rail and the insulating material is not particularly limited.
