Description

Technical Field

[0001] The invention belongs to the technical field of Thomson scattering experiments, and in particular relates to an angle adjustment device with a shock-absorbing function for Thomson scattering experiments. Background Art

[0002] Laser Thomson diagnostics is a diagnostic system independently developed by the EAST Thomson scattering diagnostics group. Its diagnostic principle is: under low energy conditions, the electric field carried by the incident photon accelerates the charged particles in the plasma. During the acceleration process, the particles are stimulated by the incident light wave and scatter scattered light with the same wavelength as the incident light, causing the wave to scatter twice. When the particle's movement speed is much lower than the speed of light, there is no need to consider the relativistic effect of the particle. The particle will move along the direction of the incident light oscillation electric field and generate electromagnetic dipole radiation. When the direction of movement is perpendicular to the direction of the electric field, the radiation generated is the strongest, and the radiation will be polarized along the direction of the particle's movement. Therefore, from the observer's position, the spectrum scattered from this small area is a spectrum with polarization characteristics, and its scattering spectrum is similar to the long wave of Compton scattering. Since the rest mass of the particle is generally much greater than the energy of the incident photon, at this time, assuming that there is no energy and momentum transfer between the particle and the incident wave, then the secondary excitation of the photon can be considered as an elastic process. In plasma, electrons are more easily excited by incident light than ions. Therefore, as long as the wavelength of the incident wave is greater than 0.1nm, plasma can undergo Thomson scattering. For visible light and near-infrared lasers, the conditions required for Thomson scattering are very easy to achieve. The shape of the measured secondary scattering spectrum is related to the running speed of the electrons, and the measured spectrum intensity is related to the density of the electrons. The existing equipment is outside the EAST diagnostic window and is close to the device. During the discharge process of the device, the strong magnetic field and the vibration of the device itself will cause the bracket to vibrate and shift, thereby causing the distance between the optical fiber and the lens to change, resulting in a reduction in the collection of scattered photons and a decrease in diagnostic accuracy. In view of this, it is urgent to develop an angle adjustment device with a shock-absorbing function for Thomson scattering experiments. Summary of the invention
