Summary

The new diamond anvil cell has been used for optical microsope observations and synchrotron X-ray diffraction studies. It has individual heaters and individual thermocouples for the upper and lower anvils that can be controlled and can maintain temperatures with an accuracy of more or less 0.5 deg C. Low temperatures are achieved by introducing liquid nitrogen directly into the diamond anvil cell. The equation of state of water and alpha-beta quartz transition are used to determine pressure with an accuracy of more or less 1% in the aqueous samples.
