The accelerator carried out the test operation in December, 2011.
There was the considerable anxiety, because it was right after March earthquake disaster, but the accelerator comparatively smoothly worked.
Since there is a temporary repair, the accelerator is not "smooth perfectly".
But, it was able to be confirmed with that the beam supply to the users was possible.
However, a little adjustment is necessary on the beam intensity, because the situation of the accelerator changes.
The figure of the bottom is an aspect of the beam intensity in test operation of MR.
