We present an investigation of non-equilibrium effects on the reaction histories of D3He and DT near the shock front using Monte Carlo simulations. Distributions of temperature and density near the shock front are fitted based on our previous work (Front.Phys.11(6).115206), with the parameters given in the recent paper (PhysRevLett.122.035001). Considering the thermal non-equilibrium...

Modern high-intensity laser systems use off-axis-parabolic mirrors with short focal lengths to achieve highest on-target intensities. These mirrors offer the advantage of achromatic focusing while achieving small focal spots due to very small f-numbers. Adaptive optics (AO) is also commonly used to mitigate wavefront aberrations and therefore reduce deformations of the focal spot.
A typical...

In the recent experiment carried out in September 2019 in PHELIX laser facility in Darmstadt, Germany, the interaction of relativistic laser pulse with different targets namely low density CHO foams, high-Z foils and high Z-radiators was investigated.
Using different diagnostic tools especially electron-spectrometers in different angles, TLD-spectrometers and nuclear samples, it was...

The relevance of studying high-voltage nanosecond pulsed gas discharges is due to their wide practical applications such as plasma-stimulated combustion, plasma aerodynamics, plasma medicine, surface treatment. At the same time, the rich variety of physical also determines the complexity of interpretation of observed phenomena. From a practical point of view, the study of spark discharges is...

Silica is perspective material for component of powerful laser setups and new optical fibers. Damage of the light conductivity in the silica optical fiber transporting intense laser radiation leads to the absorption of energy and the appearance of a bright laser plasma with solid density. The plasma begins to move towards the radiation source, irreversibly damaging the light guide. Depending...

We report on new findings in laser electron acceleration and high intense bremsstrahlung generation in the multi MeV energy range at moderate laser intensities. The new findings demonstrate the feasibility in terms of applications in the research field of nuclear photonics.
In recent laser matter interaction experiments at PHELIX facility (GSI, Darmstadt) using special foam targets,...

Iron–oxygen (Fe-O) binary systems are of the utmost importance for planetary evolution. However, their phase diagrams and physical properties at extreme pressure and temperatures are poorly known. As an example, recent static compression experiments have demonstrated the existence of new iron oxide stoichiometries at high pressure and temperature such as FeO2 [1][2], Fe4O5 [3], Fe5O6 [4]....

Insulator-to-metal transition (IMT) in fluid warm dense hydrogen (WDH) is one of the unresolved problems of the last decades. There are a large number of experiments aimed at determining this transition, but they have a large number of disagreements among themselves.
Today, the theoretical description of experiments has come down to the use of *ab initio* methods. One of the most used is...

The easiest fusion reaction to achieve energy gain is D+T→α+n However, this reaction has the disadvantages of releasing neutrons with energy approximately 14 MeV and tritium is an unstable isotope of hydrogen One of the most promising fusion reactions, which is p+𝐵11, has been gaining considerable attention of researchers for its negligible radioactivity Unfortunately, the existing literature...

The amplification of a surface electromagnetic wave (SEW) by means of ultrarelativistic monoenergetic electron bunch running over the flat plasma surface in absence of a magnetic field is studied theoretically. It is shown that when the ratio of electron bunch number density to plasma electron number density multiplied by a powered to 5 relativity factor is much higher than 1, i.e 5 nb /np≫1...

We present a device for positron detection in the framework of quantum-electrodynamics (QED) laser experiments. This instrument is a crucial element of a large project aiming at demonstrating for the first time the creation of electron-positron pairs via the so-called Breit-Wheeler (BW) process in the laboratory. This QED phenomenon occurs when the collision of two high-energy photons gives...

Phase transition-like (PT-like) discontinuities in equilibrium spatial charge distributions of ions in non-uniform Coulomb systems is a common phenomenon in wide number of problems for equilibrium thermo-electrostatic profiles. It was shown [1-4] that such discontinuities are peculiar micro-level manifestation of phase transitions and intrinsic macro-level non-ideality elects in local equation...
