〔産業上の利用分野〕
この発明は、超電導コイル、特に、―子、陽子、イオン

法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method of winding a superconducting coil, particularly a coil used as a magnet for deflecting charged particles such as -sons, protons, and ions, and more specifically, The present invention relates to a method for reliably winding a superconducting coil having a curvature in the direction of deflection of charged particles.
ソレノイドタイプの超電導マグネットは一般に良く知ら

力制御装置のみでの調節が可能である。In the winding of this solenoid type magnet coil,
It is relatively easy to wind a coil wire by always applying tension to it, and winding is performed by applying a tension that is opposite to the electromagnetic stress during excitation. In such cases, the wire is constantly being wound around the winding section, so it is necessary to take measures such as adjusting the winding tension according to the increase in the number of winding layers, but the tension itself can always be controlled only by a tension control device. can be adjusted.
ところが、彎曲部を含む巻線部の存在したコイルの場合

めにそれができなかったのである。However, in the case of a coil that has a winding part that includes a curved part, there is no problem on the curved convex part side, but on the curved concave part side, the unwinding speed is faster on the convex part side with a longer circumference, so By the time the point moves to the recess side, the wire rod is unwound in excess, and the tension becomes zero. Therefore, winding tension cannot be applied to the curved recess, and as a result, the winding state is unstable. When a magnetic field is applied, the movement of the wire due to electromagnetic stress cannot be suppressed, resulting in quenching.
Even the slightest movement of the wire can trigger the heat generated in other parts, causing a chain reaction of heat generation in other parts, destroying the superconducting state, so tight winding is required, but due to the curved concave part, this is difficult. was not possible.
また、巻張力が途切れることによって寸法精度の確保も
不充分になると云う問題もあった。Further, there was also the problem that dimensional accuracy was insufficiently ensured due to interruptions in the winding tension.
そこで、この発明は、高性能の超電導マグネットを得る
ために、上述の問題を生じない信頼性の高い彎曲コイル
の巻線方法を提供しようとするものである。Therefore, the present invention aims to provide a highly reliable method of winding a curved coil that does not cause the above-mentioned problems, in order to obtain a high-performance superconducting magnet.
この発明は、上述の問題点を無くすため、添付図に示す

、この軸７を中心に巻枠３を回転させて巻線していくが
、巻枠を固定してその周りにサプライ側を周回させるこ
ともある。In order to eliminate the above-mentioned problems, the present invention has a supply part 2 of a coil wire 1 and a curved winding frame 3, as shown in the attached drawings.
A wire rod tension control device 5 and a wire storage device 6 are provided between the wire rod tension control device 5 and the wire storage device 6, and the wire rod that is excessively paid out during winding of the curved concave portion A of the coil is temporarily stored in the wire storage device 6. As a result, the wire is wound while constantly applying tension to the wire being wound. Reference numeral 7 in FIG. In the general case, the winding frame 3 is rotated around this axis 7 to wind the wire, but the winding frame is sometimes fixed and the supply side is made to revolve around it.
なお、例示の張力制御装置５は一般的なテンションロー
ルを用いているが、特にこれに限定されるものではない
。In addition, although the illustrated tension control device 5 uses a general tension roll, it is not particularly limited to this.

間に貯えていくことになる。The wire storage device 6 includes two sets of parallel rollers 8.8 arranged in the direction in which the wire travels, a movable roller 9 that turns the wire between them, and a load 11 that pulls the roller 9 in a direction away from the parallel rollers. The exemplary device consisting of a fixed roller 10 for transmitting the rays to the wire is simple in construction and desirable. When the wire is excessively fed out, the roller 9 pulled by the load 11 separates from the parallel rollers, and the extra length of wire is stored between the parallel rollers and the rollers.
ここで、彎曲凹部の巻線時には、線材が２点間で弓の弦

に塗布した熱又は光硬化性樹脂を線材の巻回直後に逐次
硬化させて隣接ターン層に接着させる。When winding in a curved recess, the wire is stretched between two points like a bowstring and floats up from the winding surface, so it is necessary to use a holding roller or the like to bring the wire into close contact with the winding surface. Also,
The wound wire rod is formed by impregnating the coil with resin after winding, by thermosetting resin such as epoxy resin applied to the insulation coating layer, or by coating it on the insulation coating of the wire rod as necessary. Immediately after winding the wire, the heat-curable or photo-curable resin is sequentially cured and bonded to the adjacent turn layer.
以上のようにして巻線していくこの発明の方法によれば

することにより、巻線部の正確な寸法コントロールも可
能になる。According to the method of the present invention, which winds the wire as described above, the excessively drawn out wire is stored in the wire storage device, so that the tension is not interrupted even when winding in a curved recess, and the tension is always maintained. The ability to perform applied windings results in tightly wound coils. Furthermore, by using resin to bond and integrate the wound wire, it is possible to accurately control the dimensions of the wound wire.
なお、蓄線装置による貯蓄線は、凸部側の巻回時に放出
するのが望ましい、蓄線装置が蓄線量の小さなもので済
むからである。Note that it is desirable that the wire stored by the wire storage device be discharged when the convex portion side is wound, because the wire storage device can store only a small amount of wire.

実施した。When winding a 90@bent dipole magnet coil with a radius of curvature of 400 at the center, when winding the curved recess, the wire storage device shown in the attached figure placed between the wire supply section and the winding section temporarily removes excess wire. The winding was carried out in such a way that the winding tension was applied to the entire circumference of the coil by storing wires to eliminate any interruptions in the tension.

た。In the winding without a wire storage device, tension was naturally applied on the curved convex side, but on the curved concave side, the winding tension became zero due to the extra wire drawn out, and as a result, the winding tension of the S wire section Dimensions could not be controlled and winding was virtually impossible.
これに対し、蓄線量が１．０００ｍ程度の蓄線装置を用

形を実施することも可能であった。On the other hand, the method of the present invention, which uses a wire storage device with a wire storage capacity of about 1,000 m, can apply the desired tension even when winding a curved recess, making it possible to wind wire with high dimensional accuracy. Met. Furthermore, after winding, it was also possible to carry out thermoforming to integrate the wire by using an epoxy resin provided on the insulating layer on the surface of the wire.

れる。As described above, the present invention provides a wire storage device between the supply part and the winding part of the coil wire material to store the wire material that is excessively paid out, thereby reducing the tension generated during winding of the curved recessed part. Since it has a curved part, winding tension can be applied to the entire circumference of the coil even if the wire is unwound in advance due to the influence of the convex part on the concave part side. This has the effect that a high-performance superconducting curved coil can be realized that can achieve the desired magnetic field with a small number of training sessions by ensuring a reliable winding, sufficient dimensional accuracy, and improved reliability of the winding. It will be done.
