Abstract :
Nickel and compressed rhenium powder targets have been installed in the FNAL antiproton source target station. Ni was chosen for its high melting point energy and resistance to stress wave fractures. As well, compressed powdered rhenium segments were constrained by a thin-wall Ti jacket to insure resistance to stress fractures. The p¯ yield of these new targets is compared with that of copper-the previous standard production target. The target depletion characteristics of nickel and rhenium for a beam intensity of 1.6×1012 protons per pulse are also presented
