Abstract:
1. A beam manipulating arrangement for deflecting a plurality of charged particle beams, the arrangement comprising: a first plate having a central portion defining a plurality of apertures, and a frame portion outside of the central portion, the first plate carrying a plurality of deflectors positioned in the central portion of the first plate and a switching circuitry positioned in the central portion of the first plate, wherein each of the plurality of apertures has a deflector associated therewith, the deflector being electrically connected to the switching circuitry and configured to deflect a charged particle beam traversing the aperture; a second plate disposed opposite to the first plate such that a gap is formed between the second plate and the first plate, the second plate having a central portion defining a plurality of apertures and a frame portion outside of the central portion, wherein the apertures of the second plate are registered relative to the apertures of the first plate such that the beams of charged particles may traverse the second plate and the first plate; and at least one heater thermally coupled to the frame portion of the first plate.
