    Abstract: The invention provides electron multiple beam devices (1) for probing or structuring a non-transparent specimen (20) with primary electron beams (14) with an array of electron beam sources (3) to generate multiple primary electron beams (14), an electron sensor (12) with electron sensor segments (12a) to detect electrons of the primary electron beams (14) and at least one anode (7) to direct the primary electron beams (14) towards the electron sensor (12). The electron sensor (12) serves to inspect the primary electron beams (14), calibrate the positions of the primary electron beams (14) and possibly adjust final focus length (13) and currents of the primary electron beams before or after a probing or structuring the upper surface (20a) of a non-transparent specimens (20). Further, methods to inspect primary electron beams (14), to adjust final focus lengths (13) and to calibrate the multiple electron beam device (1) are provided.

    Abstract: A charged particle beam apparatus is provided, which comprises a charged particle beam column for generating a primary charged particle beam; a focusing assembly, such as a charged particle lens, e.g., an electrostatic lens, for focusing the primary charged particle beam on a specimen; a detector for detecting charged signal particles which are emerging from the specimen; and a deflector arrangement for deflecting the primary charged particle beam. The deflector arrangement is arranged downstream of the focusing assembly and is adapted for allowing the charged signal particles passing therethrough. The detector is laterally displaced with respect to the optical axis in a deflection direction defined by the post-focusing deflector arrangement.

    Abstract: An ion beam device is described. The ion beam device includes an ion beam source for generating an ion beam, the ion beam being emitted along a first axis, an aperture unit adapted to shape the ion beam, and an achromatic deflection unit adapted to deflect ions of the ion beam having a predetermined mass by a deflecting angle. The achromatic deflection unit includes: an electric field generating component for generating an electric field, and a magnetic field generating component for generating a magnetic field substantially perpendicular to the electric field. The device further includes a mass separation aperture adapted for blocking ions with a mass different from the predetermined mass and for allowing ions having the predetermined mass to trespass the mass separator, and an objective lens having a second optical axis, wherein the second optical axis is inclined with regard to the first axis.
