Determination of integral cross sections of 3H in Al foils monitors irradiated by protons with energies ranging from 40 to 2600 MeV

The results of H-3 production in Al foil monitors (similar to 59 mg/cm(2) thickness) are presented. These foils have been irradiated in 15x15 mm polyethylene bags of similar to 14 mg/cm(2) thickness together with foils of Cr (similar to 395 mg/cm(2) thickness) and Fe-56 (similar to 332 mg/cm(2) thickness) by protons of different energies in a range of 0.04 - 2.6 GeV. The diameters of all the foils were 10.5 mm. The irradiations were carried out at the ITEP accelerator U-10 under the ISTC Project #3266 in 2006-2009. H-3 has been extracted from Al foils using an A307 Sample Oxidizer. An ultra low level liquid scintillation spectrometer Quantulus1220 was used to measure the H-3 beta-spectra and the SpectraDec software package was applied for spectra processing, deconvolution and H-3 activity determination. The values of the Al(p, x)H-3 reaction cross sections obtained in these experiments are compared with data measured at other labs and with results of simulations by the MCNP6 radiation transport code using the CEM03.03 event generator.
