    Abstract: The invention provides a charged particle beam device, an emitter module for emitting charged particle beams and a method of operation thereof. Thereby, a charged particle beam emitter (15) emitting charged particles along an optical axis (1) is realized. On the same carrier body (32), a cleaning emitter (16) for emitting charged particles approximately along the optical axis (1) is realized. Thus, an improved cleaning can be provided.

    Abstract: An electron beam window (20) is formed with six diamond panes (21) to transmit an electron beam (15). The panes (21) are formed in a cylindrical disc (17) of single crystal or of polycrystalline diamond such that each pane (21) is surrounded by a thicker integral peripheral rim (22) which conducts heat away from the panes (21). A heat sink ring (35) can be fitted to the outer cylindrical surface of the peripheral rim (22). A scanning means (36) indexes the electron beam (15) sequentially through each pane (21). The use of diamond panes reduces the electron beam energy converted to heat in each pane (21), the thicker peripheral rim (22) increases cooling of the panes (21), and the scanning movement (37) reduces the temperature rise of the panes (21).

    Abstract: A grid for use in a linear electron beam tube such as an IOT or TWT includes a grid section 3 and a mounting flange 4 between which is included an accommodation portion 5. During use, the grid section 3 becomes hot and consequently expands but the mounting flange 4 remains relatively cool being connected to a relatively massive structure. Thin flexible strips 8 of the accommodation portion 5 permit relative movement between the mounting flange 4 and the grid section 3 due to differential thermal expansion, thus minimising distortion to the grid section which might othenvise occur if it were connected directly to the mounting flange 4 and hence fixed in its outer diameter length.

    Abstract: A beam generating system for electron tubes, particularly travelling wave tubes, is formed of a beam shaping electrode and a dispenser cathode supported therein having an emission disk at its end face. A positional change of the dispenser cathode in the beam shaping electrode at different ambient temperatures is suppressed with the beam generating system, and thus a beam defocussing is avoided. According to the invention, the dispenser cathode is directly connected to the beam shaping electron and is connected below the emission disk by means of a radial cathode support. The beam generating system of this type is particularly employed in travelling wave tubes.
