我们为 KEK 12 GeV 质子同步加速器 (KEK-PS) 的新型外部质子束线开发了两种类型的抗辐射磁体。其中一种设计采用聚酰亚胺树脂预浸渍（PRP）玻璃布来绝缘磁体线圈。新的外部质子束线的大部分磁体都是使用 PRP 制造的，没有使用其他有机材料。在 KEK-PS 的现有质子束下测试了绝缘体的辐射寿命，在高达 4 × 108Gy 的辐射下未观察到严重损坏。另一种类型设计用于 1011Gy 的较高辐射剂量，这种辐射剂量通常发生在生产目标的下游。电磁线圈仅采用无机材料绝缘，如高铝水泥和石棉带。
We developed two types of radiation-resistant magnets for a new external proton beam line of the KEK 12 GeV Proton Synchrotron (KEK-PS). One was designed with the polyimide resin pre-impregnated (PRP) glass cloth to insulate the magnet coil. Most of the magnets for the new external proton beam line were manufactured using the PRP and no other organic material. The radiation life of the insulator was tested at the existing proton beam of the KEK-PS and no serious damage was observed up to 4 × 108Gy. The other type was designed for a higher radiation dose of 1011Gy which often occurs at just downstream of production targets. The magnet coil was insulated with inorganic materials only, such as high-alumina cement and asbestos tape.
