“…24 Regarding transmutation of 135 Cs, 107 Pd and 129 I based on laser-Compton scattering using 1 kW laser system, the yield of transmutation reactions was 10 8 -10 11 per hour. 8,12,23 The comparison shows that the transmutation yield obtained in this system is two orders of magnitude higher than those achieved in previous studies. This suggests great prospective potential in transmutation of long-lived fission radionuclides using high-charge relativistic e-beams from laser plasma accelerator.…”

“…Laser-based transmutations of 129 I have already been explored experimentally, 18,19 and those of 90 Sr, 93 Zr, 99 Tc, 107 Pd, 126 Sn, 135 Cs and 137 Cs have been investigated theoretically. [20][21][22][23][24][25][26][27] These studies demonstrate the transmutation reaction in moderate yield of the order of 10 4 -10 7 s -1 and hence suggest that laser-generated electrons (mainly due to the laser-ponderomotive acceleration) could be a promising tool for photonuclear studies as well as the resulting nuclear waste management.…”

Photo-transmutation of long-lived nuclear waste induced by high-charge relativistic electron beam (e-beam) from laser plasma accelerator is demonstrated. Collimated relativistic e-beam with a high charge of approximately 100 nC is produced from high-intensity laser interaction with near-critical-density (NCD) plasma. Such e-beam impinges on a high-Z convertor and then radiates energetic bremsstrahlung photons with flux approaching 10 11 per laser shot. Taking long-lived radionuclide 126 Sn as an example, the resulting transmutation reaction yield is the order of 10 9 per laser shot, which is two orders of magnitude higher than obtained from previous studies.It is found that at lower densities, tightly focused laser irradiating relatively longer NCD plasmas can effectively enhance the transmutation efficiency. Furthermore, the photo-transmutation is generalized by considering mixed-nuclide waste samples, which suggests that the laser-accelerated high-charge e-beam could be an efficient tool to transmute long-lived nuclear waste.

“…As a result, these relativistic electrons via nonlinear processes produce radiation ranging from x rays to γ rays [7]. High sensitivity imaging such as Thomson scattering uses bright x-ray bursts, γ -ray sources are used in nuclear waste management [8,9] and γ -ray sources would also aid the development of γ -γ -ray colliders [10],whichplayanimportant role in fundamental sciences.…”

Photon emission enhancement studies from the interaction of ultraintense laser pulses with shaped targets

et al. 2022

We study the photon emission by bremsstrahlung and nonlinear Compton scattering from interaction of ultraintense laser pulses with cone target and flat foil using particle-in-cell simulations. The simulations are performed for laser pulses interacting with Al and Au targets. The strength of the two mechanisms of photon emission from bremsstrahlung and nonlinear Compton scattering are compared. When an ultra-intense (I > 10 22 W/cm 2 ) laser interacts with a cone and a foil target, photon emission by bremsstrahlung is found to be comparable to that from nonlinear Compton scattering. The obtained electron energy as well as the energy and number of photons emitted were found to be higher in case of cone shaped target compared with that of a foil target. The enhanced photon emission from cone shaped target is attributed to the guiding or collimation of hot electrons towards the cone tip from the self-generated magnetic field and electrostatic field along the cone surface which pushes the hot electrons towards the tip.

“…Because the resonant energies are unique to an isotope, the emitted photons can be used as signatures for isotope identification. In addition, γ-ray beams generated by laser Compton scattering (LCS), which have been used for research on nuclear physics [26,27] and nuclear astrophysics [28] as well as industrial and medical applications [29][30][31][32][33][34], have excellent characteristics such as good directivity, a narrow-band spectrum, energy tunability, and moderate/high intensity. Owing to these unique features, the LCS γ-ray beam is regarded as a good candidate to excite NRF and thus to interrogate SNMs.…”

The smuggling of special nuclear materials (SNMs) across national borders is becoming a serious threat to nuclear nonproliferation. This paper presents a feasibility study on the rapid interrogation of concealed SNMs by combining scattering and transmission nuclear resonance fluorescence (sNRF and tNRF) spectroscopy. In sNRF spectroscopy, SNMs such as 235,238 U are excited by a wide-band photon beam of appropriate energy and exhibit unique NRF signatures. Monte Carlo simulations show that one-dimensional scans can realize isotopic identification of concealed 235,238 U when the detector array used for interrogation has sufficiently high energy resolution. The simulated isotopic ratio 235 U/ 238 U is in good agreement with the theoretical value when the SNMs are enclosed in relatively thin iron. This interrogation is followed by tNRF spectroscopy using a narrowband photon beam with the goal of obtaining tomographic images of the concealed SNMs. The reconstructed image clearly reveals the position of the isotope 235 U inside an iron rod. It is shown that the interrogation time of sNRF and tNRF spectroscopy is one order of magnitude lower than that when only tNRF spectroscopy is used and results in a missed-detection rate of 10 −3 . The proposed method can also be applied for isotopic imaging of other SNMs such as 239,240 Pu and 237 Np.
