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: Project title: Advanced 3D modeling of Laser-Produced Plasma Processes for carbon nanostructures formation and EUV nanolithography in colliding plasmas and other advanced plasma applications. Modeling of transient events in full 3D fusion reactor environment. Associated funding: NSF, PIRE grant Other Systems: Science: Laser/target interactions: Laser Produced Plasma (LPP) systems are currently being considered as the main source of 13.5 nm photons for extreme ultraviolet lithography (EUVL) which is the technology for the manufacture of next generation computer chips. Development of compact high-resolution microscopy for water and carbon rich tissues such as proteins and lipids (Water-Window microscopy) is also based of LPP systems using various target configurations for plasma producing. The efficiency of these sources will determine the cost of future devices. Detailed source optimization requires significant experimental work and very costly efforts. Advanced modeling allows to accelerate the optimization process predicting optimum conditions and parameters based on fundamental analysis of all physical processes involved. Realistic predictions can only be done using well-benchmarked models with detail description of all the processes involved in complex multi-beam laser systems. Recently, the HEIGHTS package was used for modeling of colliding plasma experiments to study nanostructures formation in the chamber at the conditions of IFE experiments. The package was used also for modeling of EUV sources produced by multiple beams. These simulations are very time consuming and require 3D detailed modeling of several physics processes. Plasma/wall interactions in magnetic fusion reactor: A fundamental issue in tokamak operation related to power exhaust during plasma instabilities is the understanding of heat and particle transport from the core plasma into the scrape-off layer and to plasma-facing materials. During abnormal and disruptive operation in tokamaks, radiation transport processes play a critical role in divertor/edge-generated plasma dynamics and are very important in determining overall lifetimes of the divertor and nearby components. This is equivalent to or greater than the effect of the direct impact of escaped core plasma on the divertor plate. We have developed and implemented comprehensive enhanced physical and numerical models in the upgraded HEIGHTS package for simulating detailed photon and particle transport in the evolved edge plasma during various instabilities. Project description: The developed models and packages will be used for 1) the analysis of edge plasma and materials response during transient events in entire fusion reactor geometry and 2) the analysis and optimization of colliding plasmas in application to carbon nanostructures formation and EUV lithography. 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 for accurate modeling of target evolution and dynamics. 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. HEIGHTS 3D LPP package will be used for modeling of colliding plasmas produced from carbon and mixed targets to study plasma characteristics in stagnation layers and to predict new structures formation in dependence on LPP multi-beam device parameters. 2. The package will be used for the analysis of new methods for EUV sources development, particularly, optimization of geometry and multiple laser parameters for producing the efficient EUV sources. 3. HEIGHTS 3D package for modeling of fusion reactor environment will be used for the analysis of power exhaust issues in various tokamaks. Improvement of the efficiency of parallel calculations will be one of the important tasks for this comprehensive package optimization. We depend highly on the use of LCRC cluster since our comprehensive packages could not run efficiently on other systems with insufficient computer resources. We would like to request 450,000 allocation hours to conduct various optimizations, benchmarking, and parametric studies of the HEIGHTS 3D packages for several projects during FY2018. ~10% of the allocation will be for non-parallel jobs Industry partnership: Project URL: Current FY Hours Used: undetermined amount New FY Requested allocation: 450000 Q1: 100000 Q2: 100000 Q3: 150000 Q4: 100000 Justification: Storage requirements: Thank You, The LCRC Accounts System
