  1. Simulation of aluminum activation experiment at CERN/CHARM, Tsuyoshi KAJIMOTO, Noriaki NAKAO, Toshiya SANAMI, Kenichi TANAKA, Satoru ENDO, Robert FROESCHL, Joint Symposium on Nuclear Data and PHITS in 2023, 2023/11/17, Without Invitation, English, Nuclear Data Division, AESJ, The experiment at CERN/CHARM was simulated for the benchmark of particle transport codes used in the radiation shielding design of high-energy accelerators. The neutron streaming was observed by $^{24}$Na production rate in aluminum samples defined at various positions from upstream to downstream of the corridor. These neutrons originated from 24 GeV/c proton beam hitting a copper target. Calculated values by two particle transport codes were compared with each other. Furthermore, the measurement of the other nuclides was investigated, and the production rate induced by proton and $\pi^{\pm}$ was checked.

Yashima, 4th International Workshop on Accelerator Radiation Induced Activation - ARIA'17, 2017/03/22, Without Invitation, English, European Spallation Source ERIC, Tunavägen 24, Lund, 22363, Sweden, The shielding of the CHARM facility includes the CERN Shielding Benchmark Facility (CSBF) situated laterally above the target that allows deep shielding penetration benchmark studies of various shielding materials. This facility has been significantly upgraded during the extended technical stop at the beginning of 2016. It consists now of 40 cm of cast iron shielding, a 200cm long removable concrete block with 3 inserts for activation samples, a material test location that is used for the measurement of the attenuation length for different shielding materials as well as for sample activation at different thicknesses of the shielding materials. Activation samples of bismuth, aluminium and indium were placed in the CSBF in September 2016 to characterize the upgraded version of the CSBF. Monte Carlo simulations with the FLUKA code have been performed to estimate the specific production yields of bismuth isotopes (206Bi, 205Bi, 204Bi, 203Bi, 202Bi, 201Bi) from 209Bi,24Na from 27Al and 115mI from 115I for these samples. The production yields estimated by FLUKA Monte Carlo simulations are compared to the production yields obtained from gamma-spectroscopy measurements of the samples taking the beam intensity profile into account. The agreement between FLUKA predictions and gamma-spectroscopy measurements for the production yields is at a level of a factor of 2.
