Abstract:
The present invention relates to e.g. a charged particle beam energy width reduction system for a charged particle beam with a z-axis along the optical axis and a first and a second plane, comprising, a first element (110) acting in a focusing and dispersive manner, a second element (112) acting in a focusing and dispersive manner, a first quadrupole element (410) being positioned such that, in operation, a field of the first quadrupole element overlaps with a field of the first element acting in a focusing and dispersive manner, a second quadrupole element (412) being positioned such that, in operation, a field of the second quadrupole element overlaps with a field of the second element acting in a focusing and dispersive manner, a first charged particle selection element (618) being positioned, in beam direction, before the first element acting in a focusing and dispersive manner, and a second charged particle selection element (616;716) being positioned, in beam direction, after the first element acting in a focusing and dispersive manner. Thereby, a virtually dispersive source-like location without an inherent dispersion limitation can be realized.
Abstract:
The invention provides a lens system for a plurality of charged particle beams. Therein, at least one common excitation coil for at least two lens modules is provided. The lens modules comprise a first pole piece, a second pole piece and at least one opening for a charged particle beam. The lens modules constitute a component and share the excitation coil. Thereby, raw material availability, processing of work pieces and symmetry conditions for the lens fields are improved.

PROBLEM TO BE SOLVED: To provide an emitter for a charged particle beam apparatus. SOLUTION: The emitter is provided with a filament (3) fixed to and extended between a first and a second support parts (2), an emitter tip part (4)mounted on the filament (3) and a stabilizing element (6) mounted on a third support part (5) and the filament (3). The first, second and third support parts (2, 5) define a triangle, and as a result, the stabilizing element (6) will be extended at least partially in the direction of crossing an extension direction of the filament at right angles.

PROBLEM TO BE SOLVED: To provide an analysis system and a charged particle beam device by which a high-speed and high-quality imaging of a test piece can be made with a short acting distance and a compact design, and contrast of the image can be increased. SOLUTION: This is a charged particle unit which deflects and energy selects charged particles of a charged particle beam. Double focus sector units 425, 425 for deflecting the charged particle beam and an energy filter 460 for forming the potential are provided, and thereby, the charged particles of the charged particle beam are changed its direction at the potential saddle point according to the energy of the charged particles.
