We replaced fixing jigs for the corrugate tube. Four brackets and six tierods were replaced one by one in turn of (1)~(10). The gaps between the top chamber and the box frame were measured near the jacks for the chamber. At begining, the jacks were released. Maximum change was 0.1mm. We measured the height of top chamber with the laser levler before and after the jig replacement. We didn't find any changes.
