A: Yes, it is not impossible. However, since it is heavy, it may be difficult with devices in hand. Furthermore it is uncertain whether continue to use a Chenkov detector. Q: How long is the stroke of the collimator scanning stage? A: 100 mm in horizontal and 50 mm in vertical. They are enough. C: Cause of the laser position drift may be air temperature rather than laser cooling water. When air temperature changes, the support of the mirrors deforms and laser path changes. C: Stabilization of the laser path will be needed to suppress the position drift.
