“…At present, most medical radioisotopes have been provided from nuclear reactors and accelerators, and they have been distributed to hospitals. A positron emitter 18 F with a half-life of 1.8 h, which is used for position emission tomography (PET), is produced by compact cyclotron accelerators located inside of hospitals. In addition to medical diagnostic scans, the radioisotopes with half-lives of several days have been used for cancer therapy.…”

We predict the production yield of a medical radioisotope 67 Cu using 67 Zn(n, p) 67 Cu and 68 Zn(n, pn) 67 Cu reactions with fast neutrons provided from laser-driven neutron sources (LDNSs).The neutrons were generated by the p+ 9 Be and d+ 9 Be reactions with high energy ions accelerated by laser-plasma interaction. We evaluated the yield to be (3.3±0.5)×10 5 atoms for 67 Cu, corresponding to a radioactivity of 1.0±0.2 Bq, for a Zn foil sample with a single laser shot. Using a simulation with this result, we estimated 67 Cu production with a high-frequency laser. The result suggests that it is possible to generate 67 Cu with a radioactivity of 270 MBq using a future laser system with a frequency of 10 Hz and 10000-s radiation in a hospital.

“…6 Neutrons have already been applied in wide areas of research because of their charge neutrality and high transmittance to most substance. Laser-driven neutron sources (LDNSs) [6][7][8][9][10][11][12][13][14][15][16][17][18] are compact sources realized by high-power lasers. LDNSs based on laser-ion acceleration include two targets.…”

“…19 With moderators such as high density polyethylene located near the second target, the fast neutrons are decelerated to epithermal, 13 thermal, 14 and cold 15 regions to adapt for the study of various science and engineering applications. LDNSs have been studied [6][7][8][9][10][11][12][13][14][15][16][17][18] for their following features: (i) each neutron pulse has a short time duration (∼ns), (ii) neutrons could be generated from a compact space smaller than 1 cm 3 , and (iii) it is possible to produce different types of radiations including x rays 20 at the same laser shot. Because of the former two features, LDNSs could be used for neutron radiography with short time and high spatial resolution.…”

“…Roth et al 6 have demonstrated imaging using fast neutrons provided from an LDNS, and various groups have studied imaging with LDNSs. 18 Yogo et al 16 have demonstrated the principle experiment of thermal neutron radiography for batteries with/without cadmium and a B 2 C sample using low energy neutrons generated from an LDNS. X-ray radiography images were taken simultaneously in this experiment to identify different elements in the samples.…”

Non-destructive inspection of water or high-pressure hydrogen gas in metal pipes by the flash of neutrons and x rays generated by laser

et al. 2022

The thermal and epithermal neutrons are powerful probes to inspect water or high-pressure hydrogen gas because of their large scattering cross-sections with protons. Laser-driven neutron source, which is able to simultaneously emit different types of radiations such as x rays, can be used for neutron and x-ray radiography in the same laser shot. In this paper, we report the demonstration of non-destructive inspection for H2O contained within a stainless steel pipe using a laser-driven thermal neutron source, where water and stainless containers are detected by neutrons and x rays, respectively. The simulation result indicates that this method can also provide the capability to measure the hydrogen density in high-pressure hydrogen gas in metal containers.

“…The ability to drive fusion reactions and to produce neutron flashes at much higher repetition rates using compact lasers is therefore of significant interest. This would, for example, open the possibility to study the astrophysical-related processes of nucleosynthesis to form heavier elements over a broad range of parameters [5] , and to study the structure and dynamics of matter by neutron spectroscopy [6] , scattering [7] , and imaging [8][9][10] . However, target engineering is required to efficiently generate the plasma conditions to drive nuclear reactions with compact joule-level lasers.…”

The interaction of intense, ultrashort laser pulses with ordered nanostructure arrays offers a path to the efficient creation of ultra-high-energy density (UHED) matter and the generation of high-energy particles with compact lasers. Irradiation of deuterated nanowires arrays results in a near-solid density environment with extremely high temperatures and large electromagnetic fields in which deuterons are accelerated to multi-megaelectronvolt energies, resulting in deuterium–deuterium (D–D) fusion. Here we focus on the method of fabrication and the characteristics of ordered arrays of deuterated polyethylene nanowires. The irradiation of these array targets with femtosecond pulses of relativistic intensity and joule-level energy creates a micro-scale fusion environment that produced $2\times {10}^6$ neutrons per joule, an increase of about 500 times with respect to flat solid CD2 targets irradiated with the same laser pulses. Irradiation with 8 J laser pulses was measured to generate up to 1.2 × 107 D–D fusion neutrons per shot.
