Idaho National Laboratory (INL) operates a mass separator that is currently producing high purity isotopes for use as internal standards for high precision isotope dilution mass spectrometry (IDMS). In 2008, INL began the revival of the vintage 1970s era instrument. Advancements thus far include the successful upgrading and development of system components such as the vacuum system, power supplies, ion-producing components, and beam detection equipment. Progress has been made in the separation and collection of isotopic species including those of Ar, Kr, Xe, Sr, and Ba. Particular focuses on ion source improvements and developments have proven successful with demonstrated output beam currents of over 10 lA 138 Ba and 350 nA 134 Ba from a natural abundance Ba source charge (*2.4 % 134 Ba). In order to increase production and collection of relatively high quantities (mg levels) of pure isotopes, several improvements have been made in ion source designs, source material introduction, and ion detection and collection. These improvements have produced isotopes of high purity ([98 %) and in quantities in the tens of micrograms per run. The instrument and results for pure isotope production for IDMS standards will be presented.
The Idaho Explosives Detection System (IEDS) was developed at the Idaho National Laboratory (INL) to respond to threats imposed by delivery trucks carrying explosives into military bases. A full-scale prototype system has been built and is currently undergoing testing. The system consists of two racks, one on each side of a subject vehicle. Each rack includes a neutron generator and an array of NaI detectors. The two neutron generators are pulsed and synchronized. A laptop computer controls the entire system. The control software is easily operable by minimally trained staff. The system was developed to detect explosives in a medium size truck within a 5-minute measurement time. System performance was successfully demonstrated with explosives at
The Idaho Explosives Detection System (IEDS) was developed at the Idaho National Laboratory (INL) to respond to threats imposed by delivery trucks carrying bulk explosives into military bases. The system consists of two platforms, one on each side of a subject vehicle. Each platform includes a neutron generator and an array of sodium iodide (NaI) detectors. The two neutron generators are pulsed and synchronized. A computer connects to the system via Ethernet and is able to control the system remotely. The system was developed to detect bulk explosives in a medium size truck within a 5-min measurement time. In 2004, a fullscale prototype IEDS was built for testing and continued development. System performance was successfully tested at the INL from November 2005 to February 2006 using different types of real explosives with a variety of cargo. Recently, the first deployable prototype system was installed at Wright-Patterson Air Force Base in Ohio and has been in operation since May 2007. The capability of passively detecting radiological material within a delivery truck has also been added.
The current and continuing needs for advanced space data processing require the critical selection and application of specially configured computer processors. This requirement generally results in unacceptable delays in software development as existing systems are typically unresponsive to required language or code generative changes. NASA/MSFC is attacking the problem of application dependent processor configuration with the MSFC conception and development of the Space Ultrareliable Modular Compuer (SUMC). The SUMC provides for tailored architecture through reconfigurable hardware design and flexible software development via microprogramming. Adaptable system and subsystem processors provide a modular systematic solution for achieving application responsive goals at both the hardware and software levels.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
