    Abstract: Provided herein are approaches for controlling particle trajectory from a beam-line electrostatic element. In an exemplary approach, a beam-line electrostatic element is disposed along a beam-line of an electrostatic filter (EF), and a voltage is supplied to the beam-line electrostatic element to generate an electrostatic field surrounding the beam-line electrostatic element, agitating a layer of contamination particles formed on the beam-line electrostatic element. A trajectory of a set of particles from the layer of contamination particles is then modified to direct the set of particles to a desired location within the EF. In one approach, the trajectory is controlled by providing an additional electrode adjacent the beam-line electrostatic element, and supplying a voltage to the additional electrode to control a local electrostatic field in proximity to the beam-line electrostatic element. In another approach, the trajectory is influenced by one or more geometric features of the beam-line electrostatic element.

    Abstract: Foreign substances present in a sample chamber are attached to or drawn close to an objective lens and an electrode disposed close to the objective lens by applying a higher magnetic field than when normally used to the objective lens and applying a higher electric field than when normally used to the electrode disposed close to the objective lens. A stage is moved such that the center of an optical axis is located directly above a dedicated stand capable of applying voltage, the magnetic field of the objective lens is turned off, and then the potential difference between the electrode disposed close to the objective lens and an electrode disposed close to the sage is periodically maximized and minimized to thereby forcibly drop the foreign substances onto the dedicated stand capable of applying voltage.

    Abstract: A charged particle filter comprises a magnetic deflector and an outer shield. The magnetic deflector has a bore along an axis thereof passing through the deflector from a specimen end to a detector end of the deflector and through which charged particles pass when in use. The deflector is formed from one or more magnets positioned around the bore in a Halbach configuration thereby generating a relatively high magnetic field strength within the bore and a relatively low magnetic field strength outside of the deflector. The deflector has a geometry defining an outer surface and an inner surface, wherein each of the outer and inner surfaces of the deflector taper towards the axis as a respective function of distance in the specimen direction along the axis. The outer shield is formed from a soft magnetic material surrounding the magnet deflector on an outer surface side of the deflector and having a projecting portion which extends in the specimen direction with respect to the magnetic deflector from the specimen end of the deflector.

    Abstract: An apparatus and method for trapping particles in a housing is disclosed. A high voltage terminal/structure is situated within a housing. A conductive material, having a plurality of holes, such as a mesh, is disposed a distance away from an interior surface of the housing, such as the floor of the housing, forming a particle trap. The conductive mesh is biased so that the electrical field within the trap is either non-existent or pushing toward the floor, so as to retain particles within the trap. Additionally, a particle mover, such as a fan or mechanical vibration device, can be used to urge particles into the openings in the mesh. Furthermore, a conditioning phase may be used prior to operating the high voltage terminal, whereby a voltage is applied to the conductive mesh so as to attract particles toward the particle trap.
