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: BG/P 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. The package has several integrated models with detailed description of main processes: energy and particles deposition, material surface and bulk thermal response and melt-layer formation and splashing, vapor and plasma magnetohydrodynamics, nano-scale surface evolution, photon line and continuum radiation transport, atomic and molecular processes of surface materials in the plasma, thermal hydraulic analysis of coolant channels inside the bulk components. HEIGHTS team areas of current analysis and developments include research for the development of magnetic fusion energy (MFE) and inertial fusion energy (IFE) reactors, discharge produced plasma (DPP) and laser produces plasma (LPP) applications at the wide range of energy intensities (e.g., 108 -1013 W/cm2 for LPP devices), different device geometries (e.g., several reactor designs for MFE, IFE, and lithography) and large variation in both time and space scales (nanoseconds to seconds in LPP and MFE respectively; nanometers in plasma facing materials and centimeters/meters in reactor walls and cavity chamber). 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. Project description: The following numerical simulations will be carried out in FY2011: 1. We will implement, test, and evaluate parallel efficiency of separate modules and whole package updated to implement Adaptive Mesh Refinement (AMR) technique in the environment of LCRC (Fusion) cluster. 2. Utilizing the updated modules for AMR techniques, HEIGHTS team will prolong simulation of plasma/wall interactions at the steady state and transient conditions in MFE reactors. Modeling results will be compared with previously obtained results and will be benchmarked with recent experimental measurements. 3. We will continue to study the physics of colliding plasmas phenomena using HEIGHTS 3D LPP package. This is a very exciting and relatively unexplored area. We are planning to model various target geometries and target materials for creating colliding plasmas, including different target design and multiple laser beams. Also orthogonally expanding plasmas produced using 2 laser beams and 2 targets will be simulated. Great physics can be discovered in this fascinating area. Calculation time for above-listed numerical simulation experiments varies and depends on many parameters such as: a) geometrical size of the problem; b) required grid refinement details; c) real time of the simulated process; d) required physical dimension of the analyzed system. 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 FY2011.
