8. An alignment method for an electromagnet in a high energy accelerator including horizontal adjustment mechanisms located at the bottom of the electromagnet, and adjusting position and posture of the electromagnet by utilizing the horizontal adjustment mechanisms comprising the steps of:
predetermining a set of restraining torques for other horizontal adjustment mechanisms than a horizontal adjustment mechanism that is subject to the operation, for restricting a direction of movement to allow only to a desired direction; and
moving the electromagnet in the horizontal direction by operating one of the horizontal adjustment mechanisms while the other horizontal adjustment mechanisms are tightly fastened by said set of restraining torques.
