Yesterday(2018.8/10):
We measured beam profile at some points around IMMT and PR3 chamber.
The first Attached Figure shows theoritical beam radius from IMC waist and the plots of measured beam profile.
In a region near IMMT1, the plots are almost consistent with theoretical curve with designed lengths and mirror curvatures.
However after IMMT2, the plots are not consistent with theory much.
Moreover the Gaussian shape of intensity distribution was little strange(Fig. 2).
We used WinCamD-LCM4 as a beam profiler.
