强流相对论电子束和靶物质相互作用时,在束的聚焦区域沉积能量,产生高温等离子体并辐射X射线。等离子体的膨胀在靶中形成冲击波,通过测量冲击波的强度来判断电子束能量沉积的情况。在实验中,我们利用光电器件记录电子束产生的轫致辐射,记下靶等离子体形成的 When a strong current relativistic electron beam interacts with a target substance, energy is deposited in the focal region of the beam, producing a high temperature plasma and radiating X-rays. The expansion of the plasma forms a shock wave in the target and the electron beam energy deposition is judged by measuring the intensity of the shock wave. In the experiment, we use the photoelectric device to record the bremsstrahlung produced by the electron beam, record the formation of the target plasma
