Targets of iron, tungsten, carbon, and calcium of areal densities 2.3 to 5.8 g/cm/sup 2/ were fabricated to high precision for a fixed-target experiment performed in 1988 at Fermilab to measure relative Drell-Yan cross sections. The experiment used 800-GeV protons at an intensity of 2 x 10/sup 12/ protons per 23-second spill. Areal densities were determined to an accuracy of approximately 1 part in 10/sup 4/. The calcium targets were vacuum-encapsulated in stainless steel by electron-beam welding. 1 ref., 5 figs., 4 tabs.
