Abstract

We describe the experimental setup, as well as results and analysis of experiments on isothermal compression of stable hydrogen isotopes, viz., protium (H₂) and deuterium (D₂), in the initial (at P₀ = 0.1 MPa) solid state up to pressure of 550 GPa using facilities based on a magnetocumulative generator and an X-ray diffraction complex including a betatron and an X-ray image recording system. We consider the points obtained on the “cold” isentrope (T₀ = 5–13 K) for protium and deuterium. The results are compared with those obtained using static and other dynamic facilities, as well as with the results of various calculations.

超高压范围内氢同位素的零点等温线分析

摘要

我们描述了初始状态（在P ₀ = 0.1 MPa时）下稳定氢同位素（即，（H ₂）和氘（D ₂））的等温压缩的实验装置以及实验结果和分析。使用基于磁累积发生器和X射线衍射复合体（包括电子感应加速器和X射线图像记录系统）的设备，最高压力可达550 GPa。我们考虑了在and和氘的“冷”等熵（T ₀ = 5-13 K）上获得的点。将结果与使用静态和其他动态设施获得的结果以及各种计算的结果进行比较。
