FIELD: roentgen engineering, in particular, engineering of x-ray emitters, possible use in high energy industrial x-ray devices, and also in customs browsing complexes. ^ SUBSTANCE: x-ray emitter contains, positioned coaxially, vacuumized semi-wave coaxial resonator, tetrode cannon with radial anode, connection element of generator with resonator in form of anchor ring shaped head and a target. First and second hollow internal semiconductors of resonator are positioned coaxially and separated from each other by high frequency gap. In first internal conductor on the side of its free end injector of electrons is positioned, cathode of which is directed towards the target. Base of second internal conductor is connected to first end wall of resonator. Tetrode cannon and radial anode are positioned between first internal conductor and second end wall of resonator. First internal conductor is connected to radial anode and rigidly connected to external conductor of resonator by means of supporting dielectric isolator positioned between them. The target is positioned in the hollow of second internal conductor or in vacuumized hollow of span tube, positioned outside the resonator coaxially to second internal conductor. ^ EFFECT: generation of high energy (over 400 keV) flow of electrons with efficiency not less than 30% at working frequency ≈ 300 MHz, increased electric durability, reliability and lifetime. ^ 8 cl, 5 dwg |
