  • Publication number: 20200225286
    Abstract: A test apparatus is configured to test a DUT that does not support synchronous control from an external circuit. A main controller is configured based on an architecture that tests a device by synchronous control with the main controller itself as the master. A MIU is configured as an interface between the main controller and the DUT. The MIU establishes asynchronous control between it and the DUT with the DUT as the master, and establishes control between it and the main controller with the main controller as the master.

  • Patent number: 10707066
    Abstract: Four main rod electrodes included in a main electrode section are disposed in a rotationally symmetric manner around an ion optical axis. Among four pre-rod electrodes included in a pre-electrode section disposed in front of the main electrode section, two are in contact with a circle of a radius r0, whereas the other two are disposed to be in contact with a circle of a radius R0 larger than r0, resulting in rotational asymmetry around the ion optical axis. Accordingly, a shape of acceptance on an x-y plane regarding positions of ions in the pre-electrode section becomes elliptical. This allows the shape of the acceptance to become gradually flat as the ions travel along the ion optical axis, reducing a mismatch between emittance of incoming ions and the acceptance on a receiving side, and relieving ion loss during ion introduction.
