Two target configurations, suitable for the Clinton P. Anderson Meson Physics Facility (LAMPF) pion production sites, are analyzed for maximum temperatures and stresses to be experienced at LAMPF's design current (800-MeV protons at 1-mA average current). A steady-state analysis is performed using the computer code TSAAS. The pulsed nature of the beam is not considered (6 percent duty). Both targets are pyrolytic graphite. One is cooled by water flowing through copper tubes bonded to the graphite; the other is cooled by water flowing through holes drilled in a copper layer bonded to the graphite. Results of both analyses indicate that the calculated maximum stresses in the heated zone and at the copper/graphite interface due to proton beam heating are substantially lower than published values of the ultimate tensile and compressive strengths of pyrolytic graphite and copper. The calculated hot-spot temperatures are below the maximum temperature allowed by evaporation loss considerations.
