(a) Photograph of the dDAC. Three piezo actuators (PZTs) are mounted between two parts of the cell. The pressure between two diamond anvils will change when three PZTs move simultaneously. (b) Several periods of pressure change on ZnSe in a dDAC at 4.8 GPa. Solid squares denote the pressure measured by ruby fluorescence. The dashed line is a periodic 1 Hz ramp wave applied to three actuators. |
