Abstract

We describe an experimental setup devoted to the study of superconducting transitions under hydrostatic high pressure. The setup combines a miniature Diamond Anvil Cell, ruby fluorescence-scale for measuring the pressure, and helium used as a pressure transmitting medium. Pressure homogeneity and shear stress free conditions were checked. Superconducting transitions are detected using an A.C. susceptibility technique. Two illustrative studies are presented: 1) the comparison of Tc(P) for lead under hydrostatic and non-hydrostatic conditions and 2) preliminary results for Tc(P) of the heavy-fermion superconductor CeCu2Si2.
