Experimental study and simulation of the residual activity induced by high-energy argon ions in copper

Activation of aluminum by argon: Experimental study and simulations

“…The total activities of 7 Be and 22 Na were obtained by integration of the corresponding depth profiles in the same manner as for previous experiments [6,7]. The resulting activities for 500 MeV/u argon ions at the end of irradiation in the thick aluminum target are (5.41 ± 0.17)Á10 À10 Bq/ion and (6.21 ± 0.32)Á10 À11 Bq/ion for 7 Be and 22 Na, respectively.…”

“…Production of 52 Mn was (1.88 ± 0.33)Á10 À7 nuclide/ ion/mm, which is in agreement with the FLUKA prediction. However, it is about 3 orders of magnitude less than production of 7 Be, 22 Na and 24 Na. Moreover, 52 Mn and 58 Co are not the products of aluminum target-nuclei.…”

“…The experimental and spectroscopic set-up was similar to the previous experiments 0168-583X/$ -see front matter Ó 2011 Elsevier B.V. All rights reserved. doi:10.1016/j.nimb.2011.03.017 [5][6][7]. Two types of targets were irradiated.…”

“…Several irradiation experiments on selected materials and under different irradiation conditions were completed. Stainless steel and copper were irradiated by 238 U +73 beams at 500 and 950 MeV/u [5,6] and copper was irradiated by 40 Ar +18 beams at 500 MeV/u and 1 GeV/u [7]. This paper presents a continuation of these experiments for aluminum irradiated by 40 Ar +18 beams having 430 and 500 MeV/u.…”

“…This paper presents a continuation of these experiments for aluminum irradiated by 40 Ar +18 beams having 430 and 500 MeV/u. Aluminum was chosen because it represents a material with relatively low atomic number (Z = 13) that is expected to get less activated than high-Z materials studied in the previous experiments [5][6][7]. Aluminum components should be preferred in accelerator areas with high beam losses (e.g.…”
