Abstract: A flash radiography diode includes a cathode and an anode. The cathode includes a frustum member with a bore extending through the frustum member. The anode is a tapered anode made of an electrically conductive material and oriented toward the cathode. The anode and the cathode are housed in a chamber with a gap between the anode and the cathode. The cathode is configured to emit electrons to the tapered anode, which electrons strike the anode and create an anode plasma. The anode plasma creates X rays which propagate from the anode.

Abstract: A medical imaging device employs a plurality of triggered plasma cathode flash X-ray sources, each of which has an axially extending round anode rod, a cathode, and a trigger electrode. The application of a trigger pulse between the electrode and the cathode produces a burst of plasma near the cathode, the plasma containing electrons that are accelerated toward and impact the anode in a region termed the "focal spot" for producing X-rays when a voltage source applies a predetermined voltage between the cathode and anode. According to the invention, a non-conducting surface interconnects the electrode with a cathode or a conductor held at the same potential as the cathode, the application of a trigger pulse to the electrode causing flashover across said surface for producing the burst of plasma.

Abstract: A plasma electron source has an apertured cathode, and a housing for defining a cavity behind the aperture. A trigger electrode, in communication with the cavity, is responsive to a short-duration trigger pulse for establishing plasma in the cavity. The plasma is sustained in the cavity subsequent to the termination of the trigger pulse by a bias circuit, which biases the cavity at a relatively low voltage with respect to the cathode for a period of time much longer than the duration of the trigger pulse.

Abstract: An improved diode for forming an intense electron beam and propagating theeam. The diode includes a cathode having a bore, and a rod-shaped anode having a medial tapered section which extends, approximately coaxially, through the bore of the cathode. The anode tapers at or near the cathode and is formed from electrically conductive material. The cathode is made from a material which rapidly emits electrons during the early stage of an applied voltage pulse. The electrons strike the anode and form a plasma thereon. Sufficient anode current and the formation of sufficient anode plasma affect the magnetic and electric fields to pinch the electrons closer to each other and to force the electron beam to propagate along the anode and away from the cathode and voltage supply. The tapered section of the anode increases the velocity of the pinch and the density of the electron beam.
Abstract translation: 用于形成强电子束并传播光束的改进的二极管。 二极管包括具有孔的阴极和具有中间锥形部分的杆状阳极，其大致同轴地延伸穿过阴极的孔。 阳极在阴极处或附近逐渐变细，并且由导电材料形成。 阴极由在施加电压脉冲的早期阶段快速发射电子的材料制成。 电子撞击阳极并在其上形成等离子体。 足够的阳极电流和足够的阳极等离子体的形成会影响磁场和电场，以将电子夹紧在彼此附近，并迫使电子束沿着阳极传播并远离阴极和电压供应。 阳极的锥形部分增加了夹子的速度和电子束的密度。
