(Summary description)The significance of studying plasma radiation lies in: on the one hand, it is an important way of energy dissipation of plasma; on the other hand, the study of plasma radiation is the necessary basis for in-depth understanding of plasma motion law by means of spectrum analysis and other methods. This is particularly important in astrophysics and space physics because the understanding of distant plasmas has been gained almost entirely through the study of radiation. The radiation of plasma includes: bremsstrahlung, cyclotron radiation, blackbody radiation, Cherenkov radiation, and linear radiation in the transition of atoms, molecules or ions. Bremsstrahlung is the collision between free electron and ion, i.e. the continuous radiation produced by electrons when the ion velocity changes in the Coulomb field. Electron-electron collisions do not change the total momentum of the electrons and therefore do not generate bremsstrahlung. Bremsstrahlung in plasma is mainly caused by distant collisions, and its wavelength generally ranges from ultraviolet to X-ray. Radiation loss is a very important problem for high temperature plasmas. Echo radiation, also known as cyclotron radiation, is the radiation produced by charged particles, mainly electrons, as they move in circles around magnetic field lines. The radiation of non-relativistic electrons is called cyclotron radiation, which is a monochromatic radiation that appears in the form of spectral lines at the electron cyclotron frequency. When the electron energy is high, in addition to the fundamental frequency, it also emits radiation in a harmonic frequency. This type of radiation is nearly isotropic and weak in energy. In the plasma, due to collision and other reasons, the spectral line becomes wider, and the frequency of the spectral line moves to the high frequency direction with the increase of the plasma density. The cyclotron radiation of relative electrons is called synchrotron radiation, which has high power, weak directivity, concentrated in a small area, and is a kind of continuous spectrum. The above is the CRF vacuum plasma spraying manufacturer to explain the plasma radiation research status, I hope to help you.
