PRM traverser recovery

[Ikeda, Fabian, Hirat, Yano, Ushiba]

Abstract:
We resolved PRM traverser problem.
The reason why the traverser didn't move is PRM traverser had fixture jig which doesn't exist on PR2 traverser.
After removing the fixture, we can smoothly move the PRM traverser.

Detail:
We checked the PRM traverser again in this morning and found that there are fixtures of linear guide on PRM traverser (fig1), which doesn't exist on PR2's (fig2).
So, we removed them and tried to move traverser.
Then, the traverser moves very smoothly by using motors.

Note:
We haven't checked the fixtures are installed on PR3 traverser, so we need to check it as some point.

According to this klog4308, there seems to be no such stopper (-X/+Y side) in PR3 at that time.

Also, no stopper (-X/+Y side) in PRM as klog3775 at that time, and in PR2 as klog6535.
