After leaving the TMS-VIS on a pallet in the Xend room at the entrance one night to make the TMS-VIS's temperature equilibrium with that of the room (Fig 1), we unpacked the aluminum barriar. Then we found three actuator coils for horizontal actuation were damaged!!
(Shown in the next post) The story was as follows:
- Some of the shims, that were inserted into the gaps between the suspenstion stage and the base structure to limit moves of the suspended stage, were slipped off.
-
Without the shims, the blade springs lifted the head up as we had removed some weight in Mitaka. Then the actuator coils, which were attached to the suspended stage, touched to the actuator yokes, which were attached to the base structre. Fortunately the amount of head-up was not so much that the bodies of the coils (partly made of PEEK) were not broken due to the head-up forces of the blade spring.
- Then vibration input during the transportation would make the suspended stage shake horizontally, and the yokes grated the electric wires on the coils.
Anyway the whole TMS-VIS structure was lifted up from the pallet by the forklift from the arm tunnel and put on the bishamon in the Xend room, then we brought it thought the EXC clean booth (Fig 3 and 4) to EXT clean room. During the transportation by the bishamon, several stucks of the bishamon's wheels happend due to very elementary misses; don't go on a soft mattered floor; use stainless steel plates to overcome steps (Fig 2)!!
Finally the TMS-VIS arrived in the EXT clean booth in the morning (Fig 5).
