The results for (bound state) energies are obtained by numerically solving the Dirac equation. The present method uses the relativistic distorted-wave approach to calculate the continuum orbitals and the ionization cross sections by photon collision. The strongly coupled semiclassical plasma effects and the plasma ion shielding effects on various properties such as ionization energies, transition rates, and photoionization cross sections are studied, focusing on the hydrogen atom as a case study.

For this purpose, smoothing techniques are used. The most commonly used, smoothing by spectral dispersion (SSD), induces temporal fluctuations of the effective amplification length of Stimulated Brillouin scattering (SBS) or Stimulated Raman scattering (SRS). These fluctuations are random from shot to shot and may thus induce unpredictable levels of the efficient laser power used in laser-plasma experiments. Increasing the modulation frequency <em>f<sub>m</sub></em> while maintaining the modulation bandwidth strongly reduces these fluctuations and even reduces the average SBS level. However, increasing <em>f<sub>m</sub></em> has also an impact on laser propagation within the laser optical components. We show that, as long as chromatic dispersion is precompensated in the front-end, FM-to-AM conversion, a detrimental propagation effect, may remain sufficiently low and that anormal FM-to-AM conversion is not sensitive to the modulation frequency. Hence, there is no important bottleneck to an increase of the modulation frequency.</p></div>","PeriodicalId":49267,"journal":{"name":"High Energy Density Physics","volume":"52 ","pages":"Article 101123"},"PeriodicalIF":1.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141478584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assume that the ion distribution functions are of an arbitrary form and develop a set of “generalized” moments, that are ordered in terms of increasing powers of centre of mass velocity, but for which the effects of shifts of centre of mass velocity (equivalent to fluid velocity in the case of Maxwellian ion distributions) are suppressed. This set of generalized moments provides the most sensitive measure of relative velocity contributions to the shape of the neutron spectrum (an effect that has been colloquially referred to as “viso”).

In contrast, fast ignition creates the hot spot through external heating. This difference allows the fast ignition approach to use a solid sphere as the fusion fuel shape. The implosion of a solid sphere is one form of laser-direct-drive slow implosion. Solid sphere fuel exhibits tolerance to hydrodynamic instability and can be mass-produced relatively easily, offering significant advantages for developing inertial fusion energy. Achieving high fuel peak and areal densities of with a solid sphere requires quasi-isentropic compression, which involves multiple shock waves. Our results show the critical role of uniform laser irradiation in initiating weak shock waves in the early phase, which is essential for forming a uniform and dense fuel core with solid spheres.
