“…2, the present preliminary result of the displacement cross section is compared with the previous experimental data and the calculation. The present data showed overestimation about 4 times of the calculation with the NRT model as similar to the previous experiment carried out lower energy [8,9]. It was also shown that the PHITS with the improved model of Nordlund showed remarkably good agreement with the experimental data.…”

“…where E is the kinetic energy of projectile, dσ/dT i is recoil atom kinetic energy distribution, T i is the kinetic energy of recoil particle i valid to maximum of T max i , E d is the effective threshold displacement energy, and ν(T i ) is the number of defects (Frenkel pairs) showing the defect production efficiency defining by a vacancy and a self-interstitial atom in the irradiated material, which is widely utilized by Norgertt-Robinson-Torrens (NRT) model [6]. Calculation result was obtained with PHITS code [8].…”

“…Since many reaction channels open above 20 MeV, the calculation codes based on the intra-nuclear cascade model are utilized to obtain the cross section. So far, the experimental data carried out Kyoto University [8] and BNL/AGS [9] are available above 20 MeV. It was reported that the displacement cross section of tungsten calculated with the MARS code [7] has 8 times difference in various calculation models.…”

For damage estimation of structural material in the accelerator facility, displacement per atom (DPA) is widely employed as an index of the damage calculated based on the displacement cross section obtained with the calculation model. Although the DPA is employed as the standard, the experimental data of displacement cross section are scarce for a proton in the energy region above 20 MeV. Among the calculation models, the difference exists about 8 times so that experimental data of the displacement cross section is crucial to validate the model. To obtain the displacement cross section, we conducted the experiment in J-PARC. As a preliminary result, the displacement cross section of copper was successfully obtained for 3-GeV proton. The present results showed that the widely utilized the Norgertt-Robinson-Torrens (NRT) model overestimates the cross section as suggested by the previous experiment for protons with lower energy.

Point defects in semiconductors are emerging as an important contender platform for quantum technology (QT) applications, showing potential for quantum computing, communication, and sensing. Indeed, point defects have been employed as nuclear spins for nanoscale sensing and memory in quantum registers, localized electron spins for quantum bits, and emitters of single photons in quantum communication and cryptography. However, to utilize point defects in semiconductors as single-photon sources for QT, control over the influence of the surrounding environment on the emission process must be first established. Recent works have revealed strong manipulation of emission energies and intensities via coupling of point defect wavefunctions to external factors such as electric fields, strain and photonic devices. This review presents the state-of-the-art on manipulation, tuning, and control of single-photon emission from point defects focusing on two leading semiconductor materials-diamond and silicon carbide.
