Application of Vacuum in Accelerator and Controlled Nuclear Fusion

Accelerator is a device that accelerates particles to obtain high energy. In the accelerator, electrons, protons, deuterium, a particles and other heavy ions of various energies can be generated. The interaction between these particles and matter can...

Application of X-ray imaging technology in defect detection of die castings

There is only one reason for shrinkage cavity and porosity of die castings, which is the inevitable phase transformation shrinkage when the liquid phase changes to the solid phase after the metal melt is filled. Because the solidification characteris...
