A three-step model for high harmonic generation from impurities in solids is developed. The process found to be similar atomic and molecular gases, with the main difference coming nonparabolic nature of bands. This opens a new avenue strong-field physics condensed-matter phase. As first application, our conceptual study demonstrates feasibility tomographic measurement impurity orbitals.
Abstract Metal-oxide interfaces of three different materials irradiated in a pressurized water reactor have been analyzed by TEM and AEM. Standard Zircaloy-4, low-tin Zr-2.5%Nb were used for this study. The microstructure the material on two sides metal-oxide interface, geometry distribution alloying elements, oxygen profile examined each material. Results examinations showed that had interface. In particular, following parameters noticed: a) interface seems to be nature case alloy. Unlike...
Whereas the Kerr nonlinearity is well understood in perturbative limit of nonlinear optics, there considerable discussion about its functional form and magnitude at extreme intensities, which point matter starts to ionize. Here, we introduce a concept answer this question theoretically analyze feasibility. We demonstrate that seeded instability amplification provides clear signatures from can be extracted non-perturbative optics.
Abstract More than 20 trace and minor elements were determined in water samples the suspended load of river Aare (Switzerland) using a simple sample preparation technique subsequent instrumental neutron activation analysis. The irradiated without preconcentration. interfering activity 24Na was eliminated with hydrated antimony pentoxide. co-precipitated as sulfides hydroxides analyzed on Ge(Li)gamma-ray spectrometers. Particulate matter filtered off field, assayed by γ-ray spectroscopy. Main...
Evolution of lasers in Kerr nonlinear materials is inextricably linked with unstable behavior.Current research has investigated the growth optical instability out noise, which results phenomena such as conical emission and filamentation bulk materials, modulation fibers.Here, we suggest that seeding dielectrics can be used for wideband amplification ranging from second harmonic pump laser to mid-infrared.Our theoretical feasibility analysis focuses on infrared.We find one-to two-cycle pulse...
Options for fuel cycle technology improvement have strongly regained attention lately with the revival of nuclear energy production interests and plans next generation systems. Various forms, geometries paths are being looked at. Within FUJI collaboration program among Japan Atomic Energy Agency (JAEA, former JNC), Paul Scherrer Institute (PSI, Switzerland) Nuclear Research Consultancy Group (NRG, Netherlands) plutonium neptunium mixed oxide- (sphere-pac- vipac-) particle fuels (20 wt% Pu, 5...
Today more than 400 light water power reactors (LWRs) operate worldwide providing approximately 17% of the world's electricity demand. One important component for their successful operation is fuel tube, made out a zirconium alloy. A huge number out-of-pile and in-pile experiments have been performed to improve step by higher burn-up reduce failure rates pins close zero. The influencing parameters excellent or poor cladding behaviour are numerous sometimes counteract each other. process...
Secondary Ion Mass Spectrometry (SIMS) is a suitable technique to evaluate the relative isotopie Gd distribution across fuel pellets.It faster and provides greater lateral resolution than microdrilling techniques.Measurements on polished cross sections with 2 0 3 contents of 7 wt%, an initial 235 U enrichment about 3.5 % burnup values between 6 GWd/tM were performed.In spite cracked porous surfaces, repeated measurements same sample lay within span less 15% (relative), provided that residual...
