International Space Station: Significant Challenges May Limit Onboard Research (open access)

International Space Station: Significant Challenges May Limit Onboard Research

A letter report issued by the Government Accountability Office with an abstract that begins "In 2010, after about 25 years of work and the expenditure of billions of dollars, the International Space Station (ISS) will be completed. According to the National Aeronautics and Space Administration (NASA), the ISS crew will then be able to redirect its efforts from assembling the station to conducting research. In 2005, Congress designated the ISS as a national laboratory; in addition, the NASA Authorization Act of 2008 required NASA to provide a research management plan for the ISS National Laboratory. In light of these developments, the Government Accountability Office (GAO) was asked to review the research use of the ISS. Specifically, GAO (1) identified how the ISS is being used for research and how it is expected to be used once completed, (2) identified challenges to maximizing ISS research; and (3) identified common management practices at other national laboratories and large science programs that could be applicable to the management of the ISS. To accomplish this, GAO interviewed NASA officials and reviewed key documents related to the ISS. GAO also studied two ground-based national laboratories and several large science institutions."

Office of Human Radiation Experiments

This website is the result of a project started in 1994 by the Department of Energy's Office of Human Radiation Experiments. The purpose of the group was to research experiments done to test the effects of radiation on humans and to compile documentation (including photographs, oral histories, declassified documents, and audio/visual clips) about the projects, making them available online in a single place. In addition to the different documentation that was cataloged, the group also published a report discussing the process and result of their research.

On-Axis Brilliance and Power of In-Vacuum Undulators for the Advanced Photon Source. (open access)

On-Axis Brilliance and Power of In-Vacuum Undulators for the Advanced Photon Source.

A request for studying the spectral performance of in-vacuum undulators (IVUs) for the APS storage ring was recently put forward. In-vacuum undulators are prevalent at other synchrotron radiation facilities such as the ESRF and the Spring-8. However, they never made it into the arsenal of undulators at the APS because the brilliance tuning curves were sufficiently wide due to the fact that the undulator minimum gap could be set as low as 10.5 mm. For sector 3, which in the past used a narrow-gap vacuum chamber, the minimum undulator pole gap was allowed to be set as low as 8.5 mm, providing contiguous tuning curves between the first and third harmonic radiation for a 2.7-cm-period device. (Subsequently, the narrow-gap vacuum chamber was removed and replaced with a standard vacuum chamber, which allows a minimum gap of 10.5 mm.) For sector 4, which currently holds the only narrow-gap vacuum chamber at the APS, the minimum gap is 9.5 mm. In this sector, a permanent magnet hybrid undulator with SmCo magnets is used instead of NdFeB magnets because of their higher radiation resistance and their better protection against radiation-induced demagnetization of the magnets. In the realm of looking to the future, new …

Heats of vaporization of room temperature ionic liquids by tunable vacuum ultraviolet photoionization (open access)

Heats of vaporization of room temperature ionic liquids by tunable vacuum ultraviolet photoionization

The heats of vaporization of the room temperature ionic liquids (RTILs) N-butyl-N-methylpyrrolidinium bistrifluorosulfonylimide, N-butyl-N-methylpyrrolidinium dicyanamide, and 1-butyl-3-methylimidazolium dicyanamide are determined using a heated effusive vapor source in conjunction with single photon ionization by a tunable vacuum ultraviolet synchrotron source. The relative gas phase ionic liquid vapor densities in the effusive beam are monitored by clearly distinguished dissociative photoionization processes via a time-of-flight mass spectrometer at a tunable vacuum ultraviolet beamline 9.0.2.3 (Chemical Dynamics Beamline) at the Advanced Light Source synchrotron facility. Resulting in relatively few assumptions, through the analysis of both parent cations and fragment cations, the heat of vaporization of N-butyl-N-methylpyrrolidinium bistrifluorosulfonylimide is determined to be Delta Hvap(298.15 K) = 195+-19 kJ mol-1. The observed heats of vaporization of 1-butyl-3-methylimidazolium dicyanamide (Delta Hvap(298.15 K) = 174+-12 kJ mol-1) and N-butyl-N-methylpyrrolidinium dicyanamide (Delta Hvap(298.15 K) = 171+-12 kJ mol-1) are consistent with reported experimental values using electron impact ionization. The tunable vacuum ultraviolet source has enabled accurate measurement of photoion appearance energies. These appearance energies are in good agreement with MP2 calculations for dissociative photoionization of the ion pair. These experimental heats of vaporization, photoion appearance energies, and ab initio calculations corroborate vaporization of these RTILs as intact cation-anion ion …
