Summary

A DIAMOND ANVIL TYPE HIGH-PRESSURE CELL FOR A LOW-TEMPERATURE EXPERIMENT WITH AN OPTICAL SYSTEM IS DESCRIBED. THE DIAMOND ANVIL TYPE PRESSURE CELL IS ACTUATED BY HELIUM GAS IN THE CRYOSTAT AT LOW TEMPERATURES. THE OPTICAL SYSTEM IS FOR THE PRESSURE CALIBRATION AT LOW TEMPERATURES BY THE USE OF THE RUBY FLUORESCENCE METHOD AND FOR IN SITU DIRECT OBSERVATION OF THE SAMPLE AT LOW TEMPERATURES. A PRESSURE MORE THAN 40 GIGAPASCALS HAS BEEN CONTINUOUSLY GENERATED AND THE PRESSURE IS DETERMINED IN SITU BY THE RUBY SCALE WITH AN ACCURACY OF 0.3 BELOW 35 GIGAPASCALS AND 0.6 ABOVE 35 GIGAPASCALS.
