Passive Measurement of Hydrogen Ground State Rotational and Vibrational Temperatures in Kinetic Plasmas (open access)

Passive Measurement of Hydrogen Ground State Rotational and Vibrational Temperatures in Kinetic Plasmas

A dipole-quadrupole electron-impact excitation model, consistent with molecular symmetry rules, is presented to fit ro-vibronic spectra of the hydrogen Fulcher-α Q-branch line emissions for passively measuring the rotational temperature of hydrogen neutral molecules in kinetic plasmas with the coronal equilibrium approximation. A quasi-rotational temperature and quadrupole contribution factor are adjustable parameters in the model. Quadrupole excitation is possible due to a violation of the 1st Born approximation for low to medium energy electrons (up to several hundred eV). The Born-Oppenheimer and Franck-Condon approximations are implicitly shown to hold. A quadrupole contribution of 10% is shown to fit experimental data at several temperatures from different experiments with electron energies from several to 100 eV. A convenient chart is produced to graphically determine the vibrational temperature of the hydrogen molecules from diagonal band intensities, if the ground state distribution is Boltzmann. Hydrogen vibrational modes are long-lived, surviving up to thousands of wall collisions, consistent with multiple other molecular dynamics computational results. The importance of inter-molecular collisions during a plasma pulse are also discussed.

Unauthorized Alien Students, Higher Education, and In-State Tuition Rates: A Legal Analysis (open access)

Unauthorized Alien Students, Higher Education, and In-State Tuition Rates: A Legal Analysis

Currently, federal law prohibits states from granting unauthorized aliens certain postsecondary educational benefits on the basis of state residence, unless equal benefits are made available to all U.S. citizens. This prohibition is commonly understood to apply to the granting of "in-state" residency status for tuition purposes. In the 110th Congress, several bills that would amend this federal law have been introduced. Meanwhile, some states have passed laws aimed at making unauthorized state residents eligible for in-state tuition without violating this provision. This report provides a legal overview of cases involving immigrant access to higher education, as well as an analysis of the legality of state laws that make in-state tuition rates available to illegal immigrants.

Extreme Radiation Hardness and Space Qualification of AlGaN Optoelectronic Devices (open access)

Extreme Radiation Hardness and Space Qualification of AlGaN Optoelectronic Devices

Unprecedented radiation hardness and environment robustness are required in the new generation of high energy density physics (HEDP) experiments and deep space exploration. National Ignition Facility (NIF) break-even shots will have a neutron yield of 1015 or higher. The Europa Jupiter System Mission (EJSM) mission instruments will be irradiated with a total fluence of 1012 protons/cm2 during the space journey. In addition, large temperature variations and mechanical shocks are expected in these applications under extreme conditions. Hefty radiation and thermal shields are required for Si and GaAs based electronics and optoelectronics devices. However, for direct illumination and imaging applications, shielding is not a viable option. It is an urgent task to search for new semiconductor technologies and to develop radiation hard and environmentally robust optoelectronic devices. We will report on our latest systematic experimental studies on radiation hardness and space qualifications of AlGaN optoelectronic devices: Deep UV Light Emitting Diodes (DUV LEDs) and solarblind UV Photodiodes (PDs). For custom designed AlGaN DUV LEDs with a central emission wavelength of 255 nm, we have demonstrated its extreme radiation hardness up to 2x1012 protons/cm2 with 63.9 MeV proton beams. We have demonstrated an operation lifetime of over 26,000 hours in a nitrogen …

2010 Resubmission of the U.S.-Russia Nuclear Cooperation Agreement: Further Actions Needed by State and Other Agencies to Improve the Review of the Classified Nuclear Proliferation Assessment

Correspondence issued by the Government Accountability Office with an abstract that begins "On May 10, 2010, the President resubmitted to Congress a proposed Agreement Between the Government of the United States of America and the Government of the Russian Federation for Cooperation in the Field of Peaceful Uses of Nuclear Energy (henceforth referred to as the U.S.-Russia nuclear cooperation agreement or the agreement) in accordance with the review requirements established under section 123 of the Atomic Energy Act of 1954 (AEA), as amended. The proposed agreement with Russia would, among other things, establish the legal basis for the Department of Energy (DOE) to work with Russia on large-scale development of nuclear energy. The United States has 25 agreements in force for peaceful nuclear cooperation with foreign countries, the European Atomic Energy Community (EURATOM), the International Atomic Energy Agency (IAEA), and Taiwan. Such agreements provide the framework and authorization for civilian nuclear cooperation but do not guarantee that cooperation will take place or that nuclear material or technology transfers will occur. On May 13, 2008, President Bush originally submitted the agreement to Congress with the statutorily required presidential determination that this agreement would promote, and would not constitute an unreasonable risk …

Defense Exports: Reporting on Exported Articles and Services Needs to Be Improved

A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. government exports billions of dollars of defense articles and services annually to foreign entities, generally through direct commercial sales (DCS) from U.S. companies under licenses issued by the State Department (State) or through the Department of Defense (DOD) Foreign Military Sales (FMS) program. GAO has previously reported on weaknesses in the export control system. As requested, GAO (1) identified the magnitude and nature of defense articles and services exported and (2) assessed information currently reported on defense exports and any gaps and limitations in defense export data. To conduct this work, GAO analyzed export data from DOD for FMS and the Department of Commerce's U.S. Census Bureau (Census) for DCS for 2005 through 2009; reviewed relevant laws and regulations; assessed State and DOD reports on defense exports; reviewed agency data systems documentation; and interviewed officials from State, DOD, Homeland Security, and Census."

Temporary Assistance for Needy Families: Implications of Caseload and Program Changes for Families and Program Monitoring (open access)

Temporary Assistance for Needy Families: Implications of Caseload and Program Changes for Families and Program Monitoring

Testimony issued by the Government Accountability Office with an abstract that begins "The Temporary Assistance for Needy Families (TANF) program, created in 1996, is one of the key federal funding streams provided to states to assist women and children in poverty. A critical aspect of TANF has been its focus on employment and self-sufficiency, and the primary means to measure state efforts in this area has been TANF's work participation rate requirements. Legislative changes in 2005 were generally expected to strengthen these work requirements. Given changes in the number of families participating in TANF over time and questions about whether the program is achieving its goals, this testimony draws on previous GAO work to focus on 1) key changes to state welfare programs made in response to TANF and other legislation and their effect on caseload trends; 2) how low-income single-parent families are faring; and 3) how recent developments in state programs and the economy may affect federal monitoring of TANF. To address these issues, in previous work conducted from November 2008 to May 2010, GAO analyzed state data reported to the Department of Health and Human Services; used microsimulation analyses; surveyed state TANF administrators in 50 states and the …

Effects of Hyperbolic Rotation in Minkowski Space on the Modeling of Plasma Accelerators in a Lorentz Boosted Frame (open access)

Effects of Hyperbolic Rotation in Minkowski Space on the Modeling of Plasma Accelerators in a Lorentz Boosted Frame

Laser driven plasma accelerators promise much shorter particle accelerators but their development requires detailed simulations that challenge or exceed current capabilities. We report the first direct simulations of stages up to 1 TeV from simulations using a Lorentz boosted calculation frame resulting in a million times speedup, thanks to a frame boost as high as gamma = 1300. Effects of the hyperbolic rotation in Minkowski space resulting from the frame boost on the laser propagation in the plasma is shown to be key in the mitigation of a numerical instability that was limiting previous attempts.
