Integrated powder XRD patterns of Cr at the lowest (a) and the highest (b) P reached in the present experiment and their corresponding image plates (c,d), respectively.The different coloured asterisks are indicating the peaks from the Re gasket. The empty green symbol labels the peak obtained from solid He. The pattern in (a) was collected before the He loading and the DAC was positioned to obtain only the signal from Cr. In (c), the DAC was positioned to obtain signal from both Cr and W (the pressure standard) simultaneously.
