  • Field emission X-ray source device
    Patent number: 12609262
    Abstract: Proposed is a field emission X-ray source device including an insulating housing, an anode electrode, a cathode electrode, a gate electrode, an electronic emitter, and a target. The insulating housing extends in a tube shape. The anode electrode covers a first side of the insulating housing. The cathode electrode is placed at a second side of the insulating housing and faces the anode electrode. The gate electrode covers the second side of the insulating housing, and has an opening formed in the direction of the second side. The electronic emitter is provided on the cathode electrode and is configured to emit an electron beam toward the anode electrode. The target is provided on the anode electrode and is placed to face the electronic emitter, and enables X-rays to be generated by collision with the electron beam.
