We used the laser to align the degrader (see attached photos)
According to the LISE calculation, equivalent effective thickness for 6 mm of Carbon target is 4.5 mm thick Aluminum.
Therefore, we've set the degrader system as follow:
|
No

Center Position(maybe a little shift)
|
Remove Position(maybe a little shift)
