    Abstract
  • According to the requirements of target structure design and experimental data processing in multilayer target quasi-isentropic compression experiments, an interlayer transfer method for multilayer targets was proposed based on the backward integration method, the backward calculation of multilayer targets from the measuring surface to the loading surface or laser ablation surface was realized. Through the forward and backward integration numerical experiments and the application in laser driven experiment, the effectiveness of the backward integration method in multilayer targets was verified, and the backward integration processing accuracy of multilayer targets can reach within 1% in most of the calculation area. The waveform design of quasi-isentropic compression multilayer target experiments was carried out by backward integration method, and the influence of multilayer targets with different thicknesses of glue on quasi-isentropic compression experiments was analyzed.
