During 2022 FY year we performed phase-contrast imaging (PCI) experiments at High Energy Density platform of SACLA XFEL(BL3) in the frames of 4 accepted proposal. Our the PCI method was further upgraded. Now the radiographic scheme operates in multi-imaging acquisition regime. The images of the object are recorded at three different distances from the object to detectors. At every distance the PCI effect is optimized for the specific absorption and scattering properties of the object. That improvement allowed to advance the quality and informative of radiography in the wide range of density variations and to increase the accuracy of density measurements.By this method, we studied the complicated morphology of the high-energy-laser-induced shocks formed under pressure up to a few Mbar for numerous crystalline and amorphous materials of interest of precise determination parameters for equations of state (EOS) and for astrophysics related tasks (alfa-quartz, z-cut quartz, fused silica, Al, magnesium silicate Mg2SiO4, MgSiO2 glass ceramic).We continued investigation of shock induced phenomena in diamond, in particular, the slip failure mechanism. In crystalline diamonds with three different orientations <100>, <110>, and <111> were examined on the difference in plasticity mediated by shock-induced defects.In theory and simulations, for dynamic of elastic-plastic shock waves splitting in diamond the impressive matching obtained by 2D modeling using Smoothed Particle Hydrodynamics code. Developed the diffraction based model for measuring width of rising front in shock waves.

在2022财年，我们在4个接受建议的框架中，在SACLA XFEL（BL3）的高能量密度平台上进行了相位对比度成像（PCI）实验。我们的PCI方法进一步升级。现在，射线照相方案在多成像采集方面运行。对象的图像记录在对象到检测器的三个不同距离。在每个距离上，PCI效应都用于对象的特定吸收和散射特性。这种改进可以在广泛的密度变化中提高射线照相的质量和信息，并提高密度测量的准确性。通过这种方法，我们研究了在压力下形成的高能激光诱导的震动的复杂形态，最高的MBAR与少数MBAR相关的MBAR及其对精确的材料相关的属性（对于精确的材料）进行了众多等方程（以供应等式），以实现众多等方程（erser）。 （Alfa-Quartz，Z-Cut Quartz，Fused Silica，AL，硅酸镁MG2SIO4，MGSIO2玻璃陶瓷）。我们继续研究钻石中的休克诱导现象，尤其是滑移故障机制。在具有三个不同方向<100>和<111>的晶体钻石中，在理论和模拟中检查了由电击引起的缺陷介导的可塑性差异，以动态钻石中的弹性冲击波的动态，弹性型弹性弹性的弹性性弹性性匹配是使用平滑粒子粒子流体动力学代码获得的2D建模。开发了基于衍射的模型，用于测量冲击波中升高的前沿的宽度。
