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: HEIGHTS-3D modeling of plasma material interaction during edge-localized modes (ELM) and disruptions in fusion devices. Advanced 2D and 3D Laser-Produced Plasma Processes modeling for EUV Lithography and other advanced plasma applications. Associated funding: SEMATECH Other Systems: Science: HEIGHTS 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. The package has many areas of applications. It is used to simulate the effect of plasma transient instabilities on plasma facing components in magnetic fusion reactors. This is a critical problem and a serious obstacle to the success of tokamak concept as a viable energy producing device. Most plasma instabilities will cause both surface and bulk damage to plasma-facing and structural materials. HEIGHTS is used to study self-consistently and benchmark various plasma interaction processes, to predict particle and heat intensity at chamber components surfaces, and to study the effects of plasma transient events and high power deposition on reactor walls and predicting/simulating components lifetime. Next area of research with HEIGHTS is optimization of sources for the advanced lithography that includes extreme ultraviolet (EUV) and beyond EUV (BEUV) lithography, which are perspective techniques in the development of the next generation computer chips. Numerical simulations will study various processes for photon production at 13.5 nm and 6.7 nm in efficient and optimized sources design that require detail atomic and plasma radiation physics. Project description: HEIGHTS package is being updated on continuing basis with frequent add-on of new modules, improving of developed physical models and mathematics, and revising of parallel computing methods. 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 resulting solutions. The MHD equation system is solved using the total variation diminishing scheme in the Lax–Friedrich formulation (TVD-LF). The three-dimensional Monte Carlo algorithm is developed and benchmarked for plasma particles interactions with solid and plasma matter in magnetic field in any geometrical configuration. The heat conduction and vaporization block simulates heat transfer, melting and surface vaporization of target due to various input energy sources. Heat conduction in plasma is developed using an implicit algorithm of the sparse matrix technology. The radiation transport and laser photons interaction with matter are based on the weighted Monte Carlo method. Above models in the frame of HEIGHTS package will be used for the simulation of various plasma physics applications. We will study the following state-of-the art multi-phase multi-physics engineering applications: 1. EUV lithography and beyond using both YAG and CO2 lasers, pre-pulse/main pulse, mass-limited tin targets; output in 13.5 nm range as well as in 6.5-6.7 nm range; 2. Water-Window microscopy: N2 or BN, mixed material and plasma properties, nanosecond laser beams; output in 2.48 nm and 2.88 nm; 3. Femto and nanosecond Laser Ablation mass-spectroscopy in the presence of an ambient gas: several materials, mixed material and plasma properties, the effect of plasma plume evolution on the spectrally integrated signal strength; 4. Colliding plasmas physics for various applications; 5. High-power transient plasma interactions with plasma facing and nearby components and calculation of erosion component lifetime in magnetic fusion application. We would like to request 300,000 allocation hours to conduct various optimizations, benchmarking, and parametric studies of the HEIGHTS 3D packages for several projects during FY2013.
