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.
