Ohishi, Nagano, Tanioka
Today we tried to repair IMMT1.
At first, we did some preparation.
- set a filter
- put an iris in front of the IMMT1 mirror
- made workbench horizontal
Then, we opened a flange and lock the suspension as the following order.
- Mirror
- Intermediate Mass
- upper part
After locking the suspension, we took out the suspension to the bench and removed the mirror.
This mirror is kept clean by the filters which were borrowed from Type-B team.
Finally, we started to replace screws to those not having magnetism.
We replaced some part of them.
