    摘要:

    中国科学院近代物理研究所自主研制运行于45GHz的第四代高电荷态ECR超导离子源,该离子源磁体的核心之一是Nb3Sn六极线圈。为了测试单体六极线圈经过绕制、热处理、环氧浸渍等一系列工艺过程后,电磁性能是否达到设计指标,设计了能够一定程度上模拟六极磁场及其应力分布的Mirror测试结构。由于Mirror结构在室温装配过程中采用Bladder-Key技术对六极线圈施加预应力,为了能够模拟从室温装配到冷却降温的操作流程、验证Ansys有限元仿真方法与实验结果的一致性,依据六极线圈外形尺寸加工了一个模拟线圈。实验结果表明,铝壳和模拟线圈中心处的应变与Ansys仿真计算结果基本一致,最大误差均在10%以内,验证了结构设计的合理性和仿真结果的可信性。

    Abstract:

    The fourth-generation 45GHz ECR source(FECR) is under developing in the institute of modern physics(IMP).The one core of the FECR is the sextupole Nb3Sn coil. To test the performance of the individual sextupole coil after the process of winding ,heat treatment and vacuum-impregnated,a Mirror structure based on a Bladder and Key technology during the magnet assembly is devised.In order to simulate the assembly procedure from bladder and key pre-stress at room temperature through cool-down and verity the proposed method with Ansys ,a dummy coil according to the size of the sextupole Nb3Sn coil is got.Test results of the strain in the middle of shell and dummy coil exhibits very good agreement with expected results calculated with the structural analysis program ansys,and the maximum error is less than 10%.The result verifies the rationality of the Mirror structure design and the credibility of simulation results.
