Common dual membrane pressure control assembly design
Introduction to the Device System:This device is a diamond anvil press designed with dual gas film in-situ pressure control, suitable for optical, XRD, and magnetic measurements in various temperature environments. This device can also derive pressure card sleeves suitable for multiple DACs, enabling in-situ pressure relief operations of DACs under complex working conditions such as low temperature, high temperature, or magnetic field. Combined with high-strength shells and small anvil surfaces, the maximum pressure can reach 400GPa.
