Measured cross sections of the production of tritium in thin 27 Al, nat Ni, and nat W targets irradiated with protons with energies ranging from 40 to 2600 MeV are presented. The targets in the form of single and double metal-aluminum “sandwiches” were irradiated at the ITEP-based U-10 accelerator. Tritium was extracted from the irradiated targets using the Sample Oxidizer system, and its activity was measured using a low-background liquid scintillation spectrometer. To calculate the cross sections of tritium production in the 27 Al, nat Ni, and nat W targets, its losses in the process of irradiation (geometrical correction due to target dimensions) and storage from the end of irradiation to the start of extraction (diffusion correction) were estimated. The obtained data on the tritium production cross section were used to assess the prognostic capacity of the CEM03.03 nuclear model.
