In order to control the beam current to the detector, 8 movable slits in which the position resolution of the stoppers is better than 5μm are installed along the accelerator. For the weak current measurement, 9 movable current monitors based on scintillator are installed along the beam line. These monitors can measure the very weak current, even to several electrons. The monitors can be pulled away the beam axis when the electron beam goes to the downstream.
