Abstract:

We demonstrate high repetition-rate deuteron acceleration by irradiating a continuously flowing, ambient temperature liquid heavy water jet with the high-intensity ALEPH laser. The laser delivered up to 5.5 J (120 TW, 1.2 × 1021 W/cm2) laser energy on target at 0.5 Hz. A high repetition-rate Thomson parabola spectrometer measured the deuteron beam energy spectra on each shot for 60 sequential shots (two minutes). Peak fluxes of [Formula: see text] deuterons/sr/pulse, corresponding to an average flux of [Formula: see text] deuterons/sr/min, were demonstrated with deuteron energies reaching up t

Abstract:

Abstract The recent measurements of cosmic-ray (CR) deuteron fluxes by AMS-02 show that the rigidity dependence of deuterons is similar with that of protons but flatter than 3He, which has been attributed to the existence of primary deuterons with abundance much higher than that from the Big Bang nucleosynthesis. The requirement of highly deuteron-abundant sources imposes a serious challenge to modern astrophysics since there is no known process to produce a large amount of deuterons without violating other constraints. In this work we demonstrate that the fragmentation of heavy nuclei up to n

The rate constants for deuteroxide and hydroxide catalyzed H → D and D → H exchange of benzodihydrothiophene oxide (1a) and several of its deuterated analogs 1b, 1c, and 1d at 30.00 ± 0.05 °C are reported along with the rate constants for D → H exchange of deuterated benzyl methyl sulfoxides 2b and 2c. Application of the steady-state assumption to schemes involving equilibrating pyramidal anions yield equations which are used to fit experimentally determined (kf/ks)H → D and (kf/ks)D → H ratios.

A study of acid- and base-catalyzed hydrogen isotope exchange of bicyclo[2.2.1]heptan-2-one (1a) and its 3-deuteriated analogs has been carried out.

For acid-catalyzed exchange in CH3COOD(H)–D(H)Cl the rate ratios are 156 ± 20 and 29 ± 2 for H → D and D → H exchange, respectively.

Abstract:

Knock-on deuteron imaging is a new diagnostic technique that is being implemented at the OMEGA laser facility to diagnose the morphology of an inertial confinement fusion (ICF) implosion. It utilizes the fact that some of the neutrons from deuterium–tritium (DT)-fusion reactions generated in the central hot-spot of an ICF implosion elastically scatter deuterons as they traverse the surrounding shell layer. The energy of these “knock-on” deuterons depends on the scattering angle, where the most energetic deuterons are forward-scattered and probe the shape of the central hot-spot, while lower-en

It is demonstrated that H atoms can be located by the spectroscopic method of deuteron NMR. The requirement is that the `heavy-atom' positions are known from diffraction studies.

The lack of a dedicated model for nuclear reactions of deuterons at energies below 150 MeV/n has been a long-standing shortcoming of the general-purpose radiation-transport code FLUKA, preventing its use in applications either driven by deuteron beams or where reinteracting secondary deuterons play a significant role. A dedicated modelling effort has been undertaken to overcome this limitation.

The results show that the O -D···O deuterons are indeed the basic reversible two-position dipoles in the structure and that deuteron intra-bond exchange -and thus dipole reversal transition -occurs deeply in the glass phase well below Tg where 1 D NMR techniques observe only frozen static glassy disorder.

The possibility of existence of a new type of superfluidity of the deuteron system in a metal with the number of dissolved deuterium atoms comparable with the number of atoms of the metal is discussed. If we assume that the Bose condensation of deuterons (bosons) occurs when their number density is large, the transition of the d-system to the superfluid state is possible in principle. Since deuterons are charged, such a superfluidity will be accompanied by a peculiar superconductivity.

We show, within a scheme where perturbative evolution effects are minimized, that the region around x=1 is very sensitive to these two mechanisms and their effects can be disentangled.

The irradiation of 176Yb with deuterons offers a promising pathway for the production of the theranostic radionuclide 177Lu.

Hence, 174g+mLu can be effectively filtered out by employing either a low-energy deuteron beam or stacked foils. The utilization of stacked foils enables the production of 177Lu using a high-ene

AbstractIn solid-state NMR, deuteron (2H) spectroscopy can be performed in full analogy to1H spectroscopy, including2H chemical-shift resolution and2H-X dipolar correlation schemes, when the NMR experiments are conducted in a “rotor-synchronized” fashion under fast magic-angle spinning. Here, 2H-X NMR experiments of this type, including2H-15N and2H-1H chemical-shift correlations and distance measurements, are introduced and demonstrated on cytosine monohydrate, whose acidic protons can readily be replaced by deuterons by recrystallization from D2O. In this way,2H NMR spectroscopy provides info

The International Fusion Materials Irradiation Facility - Demo Oriented NEutron Source (IFMIF-DONES) is a single-sited novel Research Infrastructure for testing, validation and qualification of the materials to be used in a fusion reactor.

The comparison between the measured spectra and the theoretical predictions is accomplished in the direct reaction region.

Abstract:

A knock-on deuteron imager (KoDI) has been implemented to measure the fuel and hotspot asymmetry of cryogenic inertial confinement fusion implosions on OMEGA. Energetic neutrons produced by D–T fusion elastically scatter (“knock on”) deuterons from the fuel layer with a probability that depends on ρR. Deuterons above 10 MeV are produced by near-forward scattering, and imaging them is equivalent to time-integrated neutron imaging of the hotspot. Deuterons below 6 MeV are produced by a combination of side scattering and ranging in the fuel, and encode information about the spatial distribution o

It is shown that at low (5 K) temperature roughly half of the protonated and one third of the deuterated H-bonds in maleate anions is extremely strong, the potential curve of the proton (deuteron) is single-well, in which the particles are located at the bond center, and the symmetry of the anions is C2v. As the temperature increases, the deuterons begin to shift toward one of the oxygen atoms at T > 30 K, and the proton at T > 100 K

The computed fluences were then compared with the reported measured values of these devices at certain distances from the pinch, where the comparison showed a good agreement including within the range of errors.
