SEE Tests With Ultra Energetic Xe Ion Beam in the CHARM Facility at CERN

Heavy Ion Nuclear Reaction Impact on SEE Testing: From Standard to Ultra-high Energies

“…5 and Fig. 6 show the LET distribution of 40 GeV/n 130 Xe and 150 GeV/n 208 Pb fragments produced on a 140 µm silicon target, respectively, which correspond to the experimental conditions in the SPS-NA at CERN [7], [8]. The LET distributions show a separated peak at 6 MeVcm 2 /mg and 15 MeVcm 2 /mg for xenon and lead respectively, which corresponds to the LET of the projectile particle.…”

“…This study is focused on the 200 MeV protons of PSI [13], the 9.3 MeV/n 20 Ne and 40 Ar ions of RADEF [14], as well as the 40 GeV/n 130 Xe and 150 GeV/n 208 Pb UHE ion beams delivered at CERN [7], [8], [26] as mentioned previously in this paper. Neon and argon ions have been chosen, because, with a LET value of 3.7 MeVcm 2 /mg and 10.1 MeVcm 2 /mg respectively, they are comparable to the UHE xenon (3.6 MeVcm 2 /mg) and lead (8.8 MeVcm 2 /mg) ions used in this study.…”

“…These simulations, dedicated to study the full transport, aimed at scoring the deposited energy in the SV [2] and convolving it with an SEL response function based on the direct ionization heavy ion data. The resulting SEL cross section compared to experimental data from several test campaigns [3], [7], [29] of the selected high-LET SEL threshold memory can be seen in Figs. 11 and 12.…”

“…In this sense, the UHE heavy ion beams provided by CERN in 2017 (xenon) and 2018 (lead) have offered the unique possibility for carrying out the mentioned tests. Two different test areas, the CERN High Energy Accelerator Mixed-Field (CHARM) [7] facility and the Super Proton Synchrotron North Experimental Area (SPS-NA) [8] xenon and lead ion beams of 6.3 GeV/n and 5.4 GeV/n, respectively, were delivered at CHARM; whereas even higher energies between 19 and 75 GeV/n for xenon and 150 GeV/n for lead were used in the SPS-NA. As will be pointed out later, these very unique beams lead to a production of projectile-like and fission fragments, when interacting with material in the beam line.…”

Ultraenergetic Heavy-Ion Beams in the CERN Accelerator Complex for Radiation Effects Testing

“…It is worth noting that during 2017 ion operation and in addition to the NA experiments described in this paper, an ion beam was used for the first time for radiation effects testing in the IRRAD/CHARM areas. The associated beam conditions and experimental results are covered in [21].…”
