titleOfInvention | Miniaturised non-radioactive electron emitter |
abstract | A non-radioactive electron emitter of simple and compact design is disclosed which is cylindrical in shape and which has an internal chamber 6 which forms a vacuum chamber. A substrate 7 forms the floor of the arrangement and has, in the internal chamber 6, a plurality of field emitter tips 5 comprising carbon nano-tubes which are secured to the substrate 7. A layered structure forms the cover of the arrangement and has, reading from the outside towards the internal chamber 6, an electrode layer 13 which acts as a counter-electrode, and which is applied to a membrane 10 which is impermeable to gases and permeable to electrons. A substrate 11 has a cutout in the form of a window 12 in the region above the field emitter tips 5 and acts as a carrier substrate for the membrane 10 and the electrode layer 13. A circumferential wall 14 formed by an electrically insulating material completes the vacuum chamber. The field emitter tips 5 and the electrode layer 13 are connected to a source 15 of DC voltage, which means that the electrons emerging from the field emitter tips 5 are accelerated through the vacuum chamber, the window 12 and the membrane 10 and onto the electrode layer 13 and pass through the electrode layer 13 and enter an ionisation area 3 outside the electron emitter 1. Further possible structures are discussed wherein extraction grids (Fig. 9, 16) are added to the apparatus so that the electron emitter may be operated in a pulsed manner. |
