The portable information terminal performs operation of a first operation item at a desired position and includes a display controller causing a display unit to display an image containing a graphical user interface (GUI) capable of operating the first operation item based on operation by a user, the first operation item being one or more operation items among a plurality of items operable in the charged particle beam irradiation apparatus.

An optical characterization system is disclosed. The optical characterization system may comprise a synchrotron source, an optical characterization sub-system, and a sensor configured to receive a projected image from a set of imaging optics. The optical characterization sub-system may include at least the set of illumination optics, a set of imaging optics, and a diffractive optical element, a temporal modulator or an optical waveguide configured to match an etendue of a light beam output by the synchrotron source to the set of illumination optics. A method of matching the etendue of a light beam is also disclosed.

Aspects of the present disclosure describe techniques for fast cooling of ion motion in a long chain using local motional modes. For example, a method is described for cooling down ions in a chain of ions that includes performing a cooling down sequence in which phonons are removed from the ions in the chain of ions by exciting and de-exciting local motional modes associated with individual ions, wherein sideband transitions that are part of the cooling down sequence are driven faster for the local motional modes than for collective motional modes for the same chain of ions; and completing the cooling down sequence when the local motional modes reach a ground state. A corresponding system and computer-readable storage medium for fast cooling of ion motion in a long chain using local motional modes are also described.
