Figure 1
Photograph (top) and schematic illustration (bottom) of the irradiation experiment for exposing pressurized heated samples to a beam of relativistic heavy ions (Lang, Lian et al., 2008). The small sample (300 µm in diameter and 40 µm thick) is enclosed in the diamond anvil cell (DAC). The inset displays the optical micrograph of a zircon crystal in the DAC. For the irradiation, the DAC is placed in air, 45 cm behind the beamline window. The schematic (not to scale) shows details of the DAC, including the resistance heating coil (only shown for one anvil). |
