Can metallic hydrogen be craeted? Pursuing the goal of making metallic hydrogen, high-pressure scientists have developped various new experimental techniques. Single-crystal synchrotron x-ray diffraction of solidified gases is one of such techniques. Recent structural studies of dense solid He demonstrate that the P-T conditions accessible to single-crystal X-ray diffraction measurement is extended to 20 GPa and 40K.
