    摘要: The invention describes a particle-optical apparatus arranged to focus a beam (1) of electrically charged particles with the aid of two particle-optical lens systems (10, 20). The lens action is achieved by magnetic fields, which fields are generated by permanent-magnetic materials (13, 23). In contrast to magnetic lenses equipped with a coil, it is not easy in the case of lenses equipped with permanent-magnetic material to alter the focusing magnetic field with the aim of altering the optical power. In an apparatus according to the invention, the optical power of the lens systems is altered by altering the energy with which the beam (1) traverses the lens systems (10, 20). This can easily happen by altering the voltage of electrical power supplies (14, 24).

    摘要: A print head has a face (6) presenting an array of nozzle orifices (7) and is configured for mounting a number of associated ejection arrangements, each ejecting droplets of printing fluid through the associated nozzle (8) when activated. The print head includes at least parts of a plurality of reservoir arrangements (27,28) for holding printing fluids to be ejected and a channel arrangement (9,14,15) for supplying a printing fluid from a reservoir arrangement (27,28) to an individual nozzle (8). The print head includes at least one adapter structure (11,13) for releasable connection to a cartridge (4; 16) including a container (5;22) for holding a printing fluid. The adapter structure (11,13) is configured to co-operate with the cartridge (4; 16) to provide a passage between the container (5;22) and channel arrangement upon connection.

    摘要: The invention relates to an apparatus for evacuating samples. A sample 4 is hereby placed in a cavity 3 of a sheet 1 with a smooth surface 2. A sole plate 5 Is placed upon this smooth surface 2, whereby the smooth surface 2 and the sole plate 5 placed thereupon together form a vacuum seal. The sole plate 5, upon which a vacuum column 6 is mounted, can be slid across the smooth surface 2. By sliding the sole plate 5 over the cavity 4, the cavity 4 is evacuated in several steps. In an embodiment of the invention, the vacuum column 6 takes the form of an ESEM (Environmental Scanning Electron Microscope). In this way, it is possible to inspect the evacuated sample 4 with the ESEM.
