Abstract

In this thesis, a gasket with two diamond windows was constructed for a Paris- Edinburgh cell (D-PEC) to enable in-situ measurements. The sample pressure was determined by means of the fluorescence peak shift of ruby and the Raman peak shift of quartz. The calibration of the sample pressure against the oil pres- sure of the D-PEC at ambient temperature was carried out up to a pressure of 5 GPa. In addition, a gasket equipped with an oven and two diamond windows was constructed, allowing to conduct experiments at temperatures up to 1000 K. This HT gasket was calibrated up to pressures of 6 GPa using fluorescence measurements of ruby and samarium-doped strontium borate and Raman mea- surements of quartz. In addition, the D-PEC was irradiated with swift heavy ions for the first time at 272 K and 0.15 GPa. Amorphization of irradiated quartz and apatite was observed.
