Description

Under MEXT Advanced Accelerator element Technology Development (ATD) program, a prototype ILC cryomodule (CM) is being designed and manufactured at KEK. The CM consists of eight 9-cell superconducting cavities, magnetic shields, power couplers, frequency tuners, a thermal shield, cooling pipes, and a superconducting magnet for beam focusing.
Due to the large number of components and strict spatial constraints, the assembly process is complex and requires careful planning.
The entire assembly process is divided into several steps, including cavity string assembly, coupler installation, and integration into the vacuum vessel. To optimize the assembly workflow and minimize risks, assembly processes for each step are being studied using detailed 3D CAD simulations. These simulations are used to evaluate component interference, tooling accessibility, and assembly sequence efficiency. This paper reports on the results of the 3D CAD-based assembly study and discusses their implication for reliable assembly of the cryomodule.
