Procurement of a Rigaku Supermini 200 Benchtop Spectrometer. 1 A00012256 Supermini200 High Powered Benchtop Wavelength-Dispersive X-ray Fluorescence Spectrometer The Supermini200 is the world’s first high powered benchtop wavelength-dispersive (WD) XRF spectrometer available. The Supermini200 provides superior sensitivity and spectral resolution resulting in low levels of detection with excellent precision and accuracy for elemental analysis from Fluorine to Uranium on the Periodic Table of Elements. Simple operation and low cost of ownership provided in a compact benchtop cabinet. •Benchtop Cabinet, 580(W)× 640mm(D)× 630mm(H), 98kg; •High Frequency X-ray Generator; •High Precision Goniometer with Temperature Stabilizer •Flow-Proportional Counter (F-PC) Detector; • Scintillation Counter (SC) Detector; •Helium Gas Flush Attachment •Windows Based Applications Software Including:Subkit for Supermini200 (SUPERMINI200-SUBKIT) •P-10 Gas Regulator (8-350); •X-ray Warning Signs (INS-XRAY-SIGNS); •Radiation Safety Handbook (HANDBOOK, NBS 111) •Periodic Table of Elements (PERIODIC TABLE) •Sample Setting Jig Helium Gas Regulator (8L-580) Included with A00012256 - 200 Watt End Window X-ray Tube, Pd Target 200 Watt End Window X-ray Tube, Pd Target The Supermini200 has been designed with optimal performance using an air-cooled 200W end window x-ray tube with a Pd target. The 200W x-ray tube results in super sensitivity while remaining a benchtop XRF 1 instrument. The tube is positioned below the sample allowing the analysis of solid, liquid, and loose powders (liquid and loose powder samples require helium purge option). No cooling water required. •50kV, 4.0mA = 200W Power •Pd Target Note: 3 Year warranty needed on X-ray Tube Included with SUPERMINI200: 12-Position Automatic Sample Changer The Supermini200 includes an easy to use bidirectional 12-position automatic sample changer to allow loading of up to 12 samples for unattended measurement. Samples may be added or removed while a sample is in the process of being analyzed. This built-in sample changer provides automation, convenience, and increased sample throughput with minimal user intervention. Sample Spin Capability •Sample spinning (30 revolutions per minute) is provided to improve sampling statistics when required. •Multipurpose Sample Holder with 30mm Mask •(3009B013), Qty 12 •Sample holder to hold any sample type; •Holes in sample holder body allow for better dispersion when used in helium atmosphere •30mm measuring area on sample surface; •Maximum sample size = 44mm outer diameter x 33mm thick •Includes Center Rings for Sample Cells 845317G Center Ring for Solid Sample 20mmH, Qty 12; 1030232 Sample Prep Kit for Supermini200 - (To be used for liquids, powders and oils) Zr Automatic Primary Beam Filter A single Zr automatic primary beam filter is included to remove the Pd-K spectral lines resulting from the Pd target x-ray tube enabling the analysis of Cd, Ru, Rh, Pd, Ag, In. 3 Crystal Exchanger Includes: LiF(200) crystal for the analysis of Ti-U PET Crystal for the analysis of Al-Ti RX-26 Multilayer Crystal O - Mg PC-XRF Computer Configuration for X-Ray Fluorescence PC Computer for instrument control and data processing.

This task order shall support the delivery of an improved version of the previously demonstrated computational methodology for generating 4d structured simplicial grids for representative aerodynamic configurations and implementing second-order edge-based finite-volume discretizations of time-dependent, inviscid-flow equations on such grids. Specifically, the contractor shall deliver the 4d structured simplicial- grid generation and edge-based solver code(s) with verified solid-wall, inflow, outflow, and farfield boundary conditions in the space-time domain. The codes shall include preprocessing and postprocessing utilities to set up the numerical simulation and analyze the results in terms of the design-order accuracy and iterative convergence. The documentation should be sufficient to allow the nasa personnel to set up, execute, and analyze the simulations, make appropriate modifications to the code if necessary, and assist with troubleshooting.
