Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Tatyana Sizyuk Project Name: HEIGHTS-3D Division: MCS Project title: Advanced 2D and 3D Laser-Produced Plasma Processes modeling for EUV and BEUV Lithography and other advanced plasma applications. Modeling of mixed materials evolution in fusion reactors. Associated funding: NSF, PIRE grant Other Systems: Science: Laser beams are being extensively developed and used for producing of sources of photons with desired energy. Laser produced plasma (LPP) devices are considered currently as the main systems for producing, e.g., extreme ultraviolet (EUV) photons for advanced nanolithography, currently being developed. Lasers with higher intensities are optimized to produce soft x-ray sources, e.g., for the development of compact and efficient microscopy for medical applications. Lasers with lower intensities are used for the spectroscopic analysis of materials based on Laser Induced Breakdown Spectroscopy (LIBS) technology. LIBS analysis is used in many important areas, e.g., detection of nuclear materials, evaluation of Mars samples, analysis of plasma facing materials evolution in fusion reactors. Intense ultra-short lasers are being developed and optimized for a wide range of applications such as nanoparticles formation, development and study of materials at high concentrations of energy. The precise analysis of ultra-short laser/matter interactions will allow the development of efficient devices for many applications. However, such analysis is still a challenging modeling and experimental task and requires accurate description of all processes evolution in ultra-short laser devices. The HEIGHTS package will be extended and used for modeling and optimization of short and ultra-short laser devices for different applications. The package is being developed as a comprehensive tool for simulation and optimization of various interaction processes during intense power deposition of various energy sources such as plasma, laser, and particle beams incident on target materials. This is multi-physics multi-phase package that combines state-of-the art models of energy deposition, vapor/plasma formation/evolution and magneto hydrodynamic (MHD) processes, thermal conduction in material and in plasma, atomic physics and resulting opacities, detailed photon radiation transport, and interaction between plasma/radiation and target material in full three dimension configurations. We use splitting methods that involve decoupling the full model into separate component for each process, employing specialized numerical methods to solve each component, and coupling the resultin g solutions. Modeling of the entire evolution of laser produced plasma in the HEIGHTS package utilizes the most suited numerical and physical models for LPP plasma, e.g., weighted Monte Carlo methods for laser deposition and plasma radiation, phase change and thermal vaporization based on surface atoms kinetics modeling, Eulerian/Lagrangian description of plasma hydrodynamic evolution in multidimensional finite volume approximation, and implicit methods for plasma thermal conduction and magnetic diffusion with sparse linear equations solvers. Plasma thermodynamic properties and optical coefficients are calculated using the self-consistent Hartree-Fock-Slater (HFS) model implemented in HEIGHTS. The populations of atomic levels, ionization balance, and the ion and electron plasma concentrations are obtained based on the collisional-radiative equilibrium (CRE) approximation. Tabulated plasma properties and optical coefficients for a wide range of temperatures and densities are used during th e simulation of whole cycle of plasma evolution in LPP. Project description: The developed models implemented in the HEIGHTS package will be extended to describe plasma evolution in femtosecond laser devices. Enhanced Monte Carlo models for the description of photons interaction with materials in different phases will be developed and integrated with continuum, two fluid systems, description of matter hydrodynamics; processes of photons and electrons distribution in sub-surface layers will be integrated with thermal evolution of target material and dynamics of developed liquid/vapor/plasma. The developed models for target ionization during ultrashort intense pulses will be integrated with detail photon transport models. The developed models will be benchmarked with in-house experiments at our CMUXE center. We will upgrade the HEIGHTS package to include detailed models for the description of laser/matter interactions in short and ultra-short laser systems with various materials and in different ambient conditions. Parallel implementation of models will be analyzed to improve the efficiency of 3D HEIGHTS package. We will study the following state-of-the art multi-phase multi-physics engineering applications: 1. Laser/mater interactions in intense ultra-short laser systems with various target materials; 2. Laser produced plasma evolution and optimization for LIBS detection of nuclear materials; 3. Fundamental LPPs analysis to find optimization ways for EUV lithography and beyond using both YAG and CO2 lasers, pre-pulse/main pulse, mass-limited tin, lithium and gadolinium targets; 4. Assessment of the difference in materials evolution under laser beam irradiation with various wavelengths in short and ultrashort pulses; 5. Colliding plasmas physics for various applications.
