KEK正在开发两种新型有机树脂，用于磁体绝缘材料。一种是氰酸酯树脂，它将代替通常的环氧树脂用于温磁绝缘。其重要特性之一是抗辐射性。我们已经开发了一种基于双马来酰亚胺-三嗪（BT）树脂的新型绝缘树脂。日本强流质子加速器复合体J-PARC的大部分磁体都是用BT树脂组装的。但是，有时BT树脂的热特性在固化阶段过于尖锐。因此，稍微中等的热特性的氰酸酯树脂作为磁体绝缘树脂可能是优越的上级。KEK已经开始了氰酸酯树脂的研发工作，并且已经取得了作为磁体绝缘体的良好效果。另一个试验是利用可以通过紫外线光硬化的树脂。因此，这种树脂被称为“UV树脂”。它们非常重要的特点是硬化速度快。一些UV树脂将在几秒钟内从光滑的液体通过UV-LED光的照射而硬化。这种现象将帮助我们组装具有非常复杂形状的暖磁体线圈。但其机械强度和辐射硬度等必须进行研究。
Two types of new organic resins are under development at KEK for the magnet insulation materials. One is Cyanate ester resins which will be used in warm magnet insulation instead of usual epoxy resins. One of its important characteristics is its radiation hardness. We have already developed a new type of the insulation resin based on Bismaleimide-Triazine (BT) resin. Most magnets of J-PARC, Japanese high intensity proton accelerator complex, were assembled with BT resin. However sometimes thermal characteristic of the BT resin was too keen at the curing stage. Therefore somewhat moderate thermal characteristics of Cyanate ester resin may be superior as magnet insulation resin. R&D work of Cyanate ester resin has started at KEK and good results as magnet insulator have already been obtained. Another trial is to utilize resins which can be hardened by Ultra Violet light. Therefore the resin is called as “UV-resin”. Their very important characteristic is its rapidness to be hardened. Some UV-resin will be hardened within several second from smooth liquid by irradiation of UV-LED light. This phenomenon will help us to assemble warm magnet coils with very much complicated shape. However its mechanical strength and radiation hardness etc. must be investigated.
