The results of a transient temperature and stress analysis of a proposed LAMPF proton target are presented. The target configuration, suitable for the LAMPF A-1, A-2, or A-5 pion production sites (800-MeV protons, 1-mA average current), is composed of pyrolytic graphite and is cooled by flowing water. Special attention is paid to the pulsed nature of the proton beam (6% duty). The computer code TSAAS is used to develop a temperature and stress history of the target during the first five beam pulses and the final, steady-state temperature distribution. The results of this analysis indicate that a conduction-cooled pyrolytic graphite target of the type shown in this report wil be suitable as a LAMPF pion production target at a beam current of 1 mA.
