Equipment for high pressure experiments at variable temperatures is described. Measurements of U(6)Fe at ambient temperatures up to 50 GPa show no phase transition. The bulk modulus (B(0) = 135 GPa) and its pressure derivative (B(0)(') = 4.4) were obtained for U(6)Fe. Measurements of Ce were performed both at ambient temperatures up to 64 GPa, and at 93 K up to 43 GPa. The tetragonal bc phase of Ce that forms above 26 GPa is unchanged in the extended pressure range, but shows less compressibility at low temperature.
