  In order to de­velop an align­ment sys­tem for the Japan Lin­ear Col­lider(JLC), we have con­structed a test fa­cil­ity to study the po­si­tion con­trol sys­tem with mul­ti­ple de­grees of free­dom for mas­sive load. No­tice­able points of the test fa­cil­ity are as fol­lows. (1) Feed­back fine align­ment sys­tem which con­sists of piezo­elec­tric ac­tu­a­tors and laser in­ter­fer­om­e­ters. (2) High-speed con­troller using VME mod­ules. (3) Level po­si­tioner dri­ven by step­ping mo­tors. The con­troller can eas­ily be con­nected with other com­put­ers by using RS-232C or Eth­er­net, so that their states such as po­si­tions can be mon­i­tored by an­other com­puter sys­tem. This fa­cil­ity achieves the align­ment of multi-de­grees of free­dom with the ac­cu­racy of the order of sub­mi­cron.
