X-ray machine is more and more widely used in the food industry, for the supply of some domestic and foreign high-end customers of the production enterprises, X-ray machine is often required by the customer must be installed equipment. We can process its Housingand internal precision parts. It can be manufactured by CNC engraving, Sand Casting, transparent acrylic(PMMA/PC) 3D Printing.
Production mode
X-rays can be produced in three ways: Bremsstrahlung, electron capture, and internal conversion, and the mechanism by which X-rays are produced by X-ray machines belongs to bremsstrahlung.
Electron capture:
Beta decay includes three ways: beta decay, beta + decay and electron capture (EC). Electron capture (EC) this decay can be expressed as that the parent nucleus captures an extranuclear orbital electron to convert a proton into a neutron, and emits a neutrino, so the charge number of the daughter nucleus becomes Z-1, while the mass number remains unchanged. In general, electrons in the K shell are mostly captured by the nucleus, because the K shell is closest to the nucleus and the probability of being captured is greatest, but the probability of being captured in the L shell also exists. After the nucleus has captured electrons, an electron vacancy will appear in the K or L shell of the daughter atom, and when an outer electron comes to fill this vacancy, one of two things may happen: The excess energy is either released in the form of signature X-rays, or it is given to another electron on the other layer, which gains energy and leaves the atom as an Auger electron. The emission of an accompanying X-ray or auger electron is a hallmark of the K capture process.
Internal conversion:
Nuclei can reach an excited state in some way (such as beta decay), and nuclei in an excited state can transition to a lower excited state or ground state by emitting gamma rays, a phenomenon called gamma decay or gamma transition. The photon emitted by the nuclear level transition and the photon emitted by the atomic level transition have no essential difference, the difference is that the energy of the photon emitted by the atomic level transition is only eV~keV order of magnitude, while the energy of the photon emitted by the nuclear level transition is MeV order of magnitude. Without considering the recoil of the nucleus, the photon energy Eg can be expressed in the form Eg=Es-Ex. Sometimes the transition of the nucleus from the excited state to the lower energy state does not emit photons, but gives energy directly to the extranuclear electron, so that the electron is removed from the atom, this phenomenon is called internal conversion (IC), and the electron from the atom is called internal conversion electron. An excited nucleus can return to the ground state by emitting gamma photons, or it can return to the ground state by producing internal conversion electrons, which process occurs completely depends on the energy level properties of the nucleus. The sum of the kinetic energy of the inner conversion electron and the ionization energy of the shell electron should be the energy difference between the two energy levels of the nucleus. Which is equal to the energy of the gamma photon emitted by the transition between the energy levels of the two atomic nuclei. The study of internal conversion is an important means to acquire knowledge about nuclear energy levels. Of course, the characteristic X-rays of atoms can also be produced by internal conversion.
