| 内容記述 | The commissioning of LIPAc (Linear IFMIF Prototype Accelerator) is ongoing at Rokkasho Fusion Institute of QST, Japan for the engineering validation of the low energy section of the accelerator up to 9 MeV. Several SRF cCryomodules are planned to be adopted in will be required for IFMIF at the downstream to accelerate deuterons from 5 MeV to 40 MeV, and . The first of these a cCryomodules will is currently being manufactured and will be installed and tested in on the LIPAc. This majority of the cryomodule Cryomodule, including the consists of 8 HWRs and RF couplers required for accelerating the beam, working at 4.45 K with 175 MHz RF and 8 RF couplers has been supplied by CEA. The and 8 superconducting solenoid magnet packages required for steering the beam will bes supplied by CIEMAT. The assembly of the cryomodule is will be completed under the responsible responsibility for of Fusion for Energy, with assembly work and has been carried out recently starting in at the QST Rokkasho site since in March 2019. In the initial plan of the project, the cryomodule was to be assembled in EU and transported to Japan. However, due to the design modification of the mechanical tuner, it was decided to perform the assembly in Japan in order to avoid a risk of damage by transportation after the assembly. Since there was no any working environment for such an assembly work in Rokkasho, Due to the cleanliness requirements for the assembly, QST took the responsibility to prepare the infrastructure of the an ISO 14644-1 class 5 cleanroom environment required for the cryomodule assembly from the scratch. A class 5 (ISO14644-1) clean room as well as some In addition, dedicated apparatus, e.g. a dedicated slow pumping system and other ancillary equipment, was prepared for the assembly. All equipment is now in operation having been installed and commissioned during 2018 and the early part of 2019. in Rokkasho so as to satisfy the requirement to provide the minimum cleaning equipment and working space just for the assembly of a cryomodule. In the present paper, the details of the preparation work for the cryomodule assembly made by QST will be presented. |
