Abstract
When an operator causes an angle change, a rotation controller controls rotation of an aperture structure with an aperture. At the same time, a deviation amount calculator calculates a positional deviation change amount based on angles of the aperture relative to a sample through rotation and deviation parameters regarding a deviation between a rotation axis of the aperture and a center of the aperture. Then the deviation amount calculator sends the positional deviation change amount to a horizontal motion controller. The horizontal motion controller controls a sample stand driving means to move a sample stand in the X-axis and Y-axis direction corresponding to the positional deviation change amount. The position of a sample is automatically adjusted to keep a spot of the sample at the center of the aperture through angle adjustment.
