    Abstract: A charged particle beam system is disclosed, comprising: a charged particle beam generator for generating a beam of charged particles; a charged particle optical column arranged in a vacuum chamber, wherein the charged particle optical column is arranged for projecting the beam of charged particles onto a target, and wherein the charged particle optical column comprises a charged particle optical element for influencing the beam of charged particles; a source for providing a cleaning agent; a conduit connected to the source and arranged for introducing the cleaning agent towards the charged particle optical element; wherein the charged particle optical element comprises: a charged particle transmitting aperture for transmitting and/or influencing the beam of charged particles, and at least one vent hole for providing a flow path between a first side and a second side of the charged particle optical element, wherein the vent hole has a cross section which is larger than a cross section of the charged particle transmitting aperture.
    Further, a method for preventing or removing contamination in the charged particle transmitting apertures is disclosed, comprising the step of introducing the cleaning agent while the beam generator is active.

    Abstract: Methods and arrangement for clamping substrates to a support using adhesive material area disclosed.The method comprises providing a support comprising a first surface defining a plane; applying adhesive material on at least portions of the first surface; and placing the substrate onto the adhesive material, wherein the adhesive material forms a plurality of support locations supporting the substrate. Preferably the adhesive material is cured at least partly during the application of a substantially uniformly distributed force to the substrate in the direction of the support.The arrangements comprise a support comprising a first surface, for supporting the substrate via adhesive material, whereby the first surface defines a plane. Preferably it also comprises an arrangement for providing electromagnetic radiation, thermal energy, and/or a chemical substance to the adhesive material, and an arrangement for providing a substantially uniformly distributed force to the substrate in the direction of the support.
