Abstract: An apparatus for focusing and for storage of ions and an apparatus for separation of a first pressure area from a second pressure area are disclosed, in particular for an analysis apparatus for ions. A particle beam device may have at least one of the abovementioned apparatuses. A container for holding ions and at least one multipole unit are provided. The multipole unit has a through-opening with a longitudinal axis as well as a multiplicity of electrodes. A first set of the electrodes is at a first radial distance from the longitudinal axis. A second set of the electrodes is in each case at a second radial distance from the longitudinal axis. The first radial distance is less than the second radial distance. Alternatively or additionally, the apparatus may have an elongated opening with a radial extent. The opening has a longitudinal extent which is greater than the radial extent.

Abstract: Producing images of a specimen includes introducing a specimen into a specimen chamber of a particle-beam device, selecting a specific position on the surface of the specimen, supplying a contrast-agent precursor on the specific position, providing a particle beam and/or a light beam, guiding the particle beam and/or the light beam onto the specific position, applying a contrast-agent layer to the specific position as a result of the interaction of the particle beam and/or the light beam with the contrast-agent precursor, leaving the contrast-agent layer on the surface of the specimen for a predetermined amount of time. During the predetermined amount of time, a first part of the contrast-agent layer diffuses into the specimen and a second part of the contrast-agent layer remains on the surface of the specimen. The specimen is imaged using an optical device and/or a particle-optical device and/or using the particle beam.

Abstract: An apparatus for transmission of energy of an ion to at least one gas particle and/or for transportation of an ion and a particle beam device having an apparatus such as this are disclosed. In particular, a container is provided, in which a gas is arranged which has gas particles, wherein the container has a transport axis. Furthermore, at least one first multipole unit and at least one second multipole unit are provided, which are arranged along the transport axis. The first multipole unit and the second multipole unit are formed by printed circuit boards. Furthermore, an electronic circuit is provided, which provides each multipole unit with a potential, such that a potential gradient is generated, in particular along the transport axis.
