Abstract

Experimental and simulation data concerning fragmentation of 238U ion beam in aluminum, copper, and stainless-steel targets with the initial energy 500 and 950 MeV/u are collected in the paper. A range-verification technique based on depth profiling of residual activity is presented. The irradiated targets were constructed in the stacked-foil geometry and analyzed using gamma-ray spectroscopy. One of the purposes of these experiments was depth profiling of residual activity of induced nuclides and projectile fragments. Among the projectile fragments, special attention is paid to the 237U isotope that has a range very close to the range of the primary 238U ions. Therefore, the depth profiling of the 237U isotope can be utilized for experimental verification of the 238U primary-beam range, which is demonstrated and discussed in the paper. The experimental data are compared with computer simulations by FLUKA, SRIM, and ATIMA, as well as with complementary experiments.
