Abstract: Provided is a charged particle beam system capable of preventing the data acquisition time from increasing. A control method for the system is also provided. The charged particle beam system includes: a beam blanker for blanking a charged particle beam; a sample stage on which a sample is tiltably held and thus can assume a tilt angle; a blanking controller for controlling the blanking of the charged particle beam and causing a pulsed beam having a duty ratio to be directed at the sample; and a tilt controller for controlling the tilt angle of the sample. The blanking controller sets the duty ratio of the pulsed beam based on the tilt angle of the sample.

Abstract: A three-dimensional image reconstruction method associated with the present invention includes the steps of: obtaining a first transmission electron microscope image of a sample containing the membrane proteins present within a lipid membrane, the image having been taken by illuminating an electron beam on the sample from a direction tilted relative to a line normal to the membrane surface of the lipid membrane; obtaining a second transmission electron microscope image of the sample taken by illuminating the electron beam on the sample perpendicularly to the membrane surface of the lipid membrane; identifying orientations of the membrane proteins of the first transmission electron microscope image on a basis of the second transmission electron microscope image; and analyzing a three-dimensional structure of the membrane proteins from the first transmission electron microscope image on a basis of information about the identified orientations of the membrane proteins.

Abstract: A state managing unit inside a line interface performs communication with a processor of both information concerning the starting and stopping of performance monitoring, and information concerning the monitoring. After entering into the state starting the monitoring, the managing unit manages by itself the state of progress of the monitoring of the performance, which state is changed by successively performing communications of OAM cells with an opposing ATM exchange, and thus autonomously executing the processing without intervention of the processor. The load on the processor is reduced and a high speed communication interface becomes unnecessary.
