26 May 1998 Evaluation of the Subaru Telescope control system in-shop test erection

On-shop test erection has been carried out at the Hitachi Zosen factory in Osaka since 1996. The purpose of this on- shop erection is to check and adjust the sizes of parts, to minimize the assembling errors, to test the telescope drive and active support system of the primary mirror, and to review the processes of final assembling. The alt-azimuth Subaru telescope structure weighting 500 ton is supported by six hydrostatic oil-film pads and is driven successfully by direct drive. The additional test for the instrument rotator drives, cable wrappers, and other were also carried out. We report the preliminary results of the control efficiency.
