Development of active mover for remote position adjustment of ILC cryomodule

International Linear Collider (ILC) is a high luminosity electron-positron accelerator. Cryomodules which consist of a cavity and thermal shields etc. are connected to each other to realize 20km long. During running the acceleration facilities, cryomodules equipped in the bunch compressor section require to fine-adjust to the vertical and horizontal direction while monitoring the condition of beams. Currently, a manual alignment system is used in test facilities. But the remote automated alignment system, named Active Movie, is required in the real structures. It's required the capability to fine-adjust within 10μm under the 12t heavy loads. Hence we propose the two methods of the Active Mover.1st is 2-CAM method which consists of 2 eccentric cams. 2nd is 2-AXIS method which consists of an eccentric cam and wedge configuration. This paper reports both designed requirements and validation of them based on the results of evaluation by the 1/7 scale mockups. (author)
