ASDEX Upgrade (AUG) is the experimental tokamak based in Germany that since many years, 1991, explores technical solutions to address physic aspects. This time, the aim is to prove that alternative divertor configurations (X-divertor or Snowflake divertor) can mitigate the power exhaust problem, in a machine with high heating power like AUG. To realize the required magnetic configurations [2], two poloidal field coils are required in the divertor region. The upgrade in AUG will be carried out in the upper divertor and the following components will be newly designed and installed in the next years: cryopump, inner and outer divertors and finally two divertor coils [4]. In the design phase, many challenges were faced: 1) Manufacturing and qualification of a conductor able to safely operate the coils [6]; 2) Implementation of the new components in a tight room, maintaining the plasma volume and the present plasma configurations; 3) Implementation of the divertor coils close to the strike line. The design has reached a certain level of maturity and a prototyping phase has been started. The installation of the component is planned for 2022 and at that time AUG will be the first tokamak having in-situ winded coils. The components design is based on the experience gained in years of AUG operation, which allowed for the building up of an extensive database to get the input parameters for the FEM analyses. Induced and halo currents interacting with the static toroidal field are the main source of loads in the structure. Different electromagnetic models were prepared to address the problem together with their corresponding mechanical models. The design has been iteratively changing according to the results of the FEM analyses. The paper will present the design of the upper divertor components and the analyses carried out to verify their mechanical integrity.

ASDEX升级（AUG）是位于德国的实验托卡马克，自1991年以来，多年来一直在探索解决物理问题的技术解决方案。这次，目的是证明在具有高加热功率的机器（如AUG）中，替代的偏滤器配置（X偏滤器或Snowflake偏滤器）可以减轻动力排放问题。为了实现所需的磁配置[2]，在偏滤器区域中需要两个极向场线圈。AUG的升级将在上分流器中进行，并在未来几年中重新设计和安装以下组件：低温泵，内分流器和外分流器，最后是两个分流器线圈[4]。在设计阶段，面临许多挑战：1）能够安全操作线圈的导体的制造和鉴定[6]；2）在密闭空间中实施新组件，保持血浆量和当前血浆配置；3）靠近触发线的偏滤器线圈的实现。设计已经达到一定的成熟度，并且已经开始了原型设计阶段。该组件的安装计划在2022年进行，届时AUG将是第一台具有原位绕组线圈的托卡马克。组件的设计基于多年AUG运行中获得的经验，这些经验允许建立一个广泛的数据库以获取FEM分析的输入参数。与静态环形场相互作用的感应电流和光晕电流是结构中载荷的主要来源。准备了不同的电磁模型以及相应的机械模型来解决该问题。根据FEM分析的结果，该设计进行了迭代更改。本文将介绍上部偏滤器组件的设计，并进行分析以验证其机械完整性。
