AbstractAbstract
[en] This paper presents a third-order single-loop delta-sigma modulator of a biomedical micro-system for portable electroencephalogram (EEG) monitoring applications. To reduce the power consumption, the loop filter of the proposed modulator is implemented by applying a switched-capacitor structure. The modulator is designed in a 0.35-μm 2P4M standard CMOS process, with an active area of 365 x 290 μm2. Experimental results show that this modulator achieves a 68 dB dynamic range with an input sinusoidal signal of 100 Hz signal bandwidth under a 64 over-sampling ratio. The whole circuit consumes 515 μW under a 2.5 V power supply, which is suitable for portable EEG monitoring.

AbstractAbstract
[en] A Portable Tritium Processing System (PTPS) has been developed at LLNL that could be applied to fusion energy related tritium processing and decontamination operations. The PTPS has four basic capabilities. These are: oil-free pumping, oil-free gas transfer, gas analysis, and gas phase tritium scrubbing. The design of the PTPS takes into consideration today's stringent release requirements, and utilizes secondary containment throughout the system. Because the system is portable, it can provide complete stand alone tritium processing, and can pass through a typical 36 inch laboratory door, and into confined spaces. This system can easily be moved to different locations within a facility such that the single tritium processing system can provide close-coupled support to multiple operations. Typical setup time for the PTPS is approximately two weeks. The PTPS has been in operation at LLNL for approximately one year. During this time, gram quantities of tritium have been successfully processed through the system. Releases to the stack attributable directly to the PTPS have been less than 0.1 curies, with most of this quantity being a product of maintenance operations

AbstractAbstract
[en] A lightweight, low-cost electron spin resonance (ESR) spectrometer utilizing Nd-Fe-B permanent magnets has been developed. The basic model is only 2 kg in weight and is now commercially available as ''Spin-X'' for educational purposes. Magnetic field modulation added to this portable spectrometer has improved the sensitivity by nearly two orders of magnitude, using a sample holder with a field modulation coil. (author)

AbstractAbstract
[en] During the operation and the decommissioning of a nuclear site the operator must assure the protection of the workers and the environment. It must furthermore identify and classify the various wastes, while optimizing the costs. At all stages of the decommissioning radiological measurements are performed to determine the initial situation, to monitor the demolition and cleanup, and to verify the final situation. The current operations for the characterization of radiological soils of CEA nuclear facilities, lead to a large increase of radiochemical analysis. To manage this high throughput of samples in a timely manner, the CEA has developed a new mobile laboratory for the clean-up of its soils, called SMaRT (Shelter for Monitoring and nuclear chemistry). This laboratory is dedicated to the preparation and the radiochemical analysis (alpha, beta, and gamma) of potentially contaminated samples. SMART is transportable via road and airline. Radiological analysis can then be performed without the disadvantages of radioactive material transport. This paper describes how this solution allows a fast response and control of costs, with a high analytical capacity. 2 dismantling projects in which SMART was used, are presented. The first one deals with a building whose soil underneath was contaminated with Ra226 and the second one deals with the dismantling of a hot cell at the CEA center in Fontenay-aux-Roses. Radiochemical Analyses were performed on site with SMART in order to detect natural or artificial contamination

AbstractAbstract
[en] Problem: Design the portable Standard Hydrogen Monitoring System (SHMS-E+) Platform with installed Bottle Racks, Pump Stand, Transformer, Chiller, and SHMS-E test cabinet. This equipment is mounted on the platform. Both Gas Bottle Racks should be designed to withstand seismic loads with adequate anchorage to the platform and the platform itself should be capable of withstanding the applicable wind and seismic loads. The platform with mounted equipment should have lifting lugs to be transported to different test sites within the tank farms. Assumptions: All equipment other than the Gas Bottle Racks, mounted on the platform will not fail or collapse when subjected to seismic and wind forces and due to transportation loads. Conclusions and recommendations: Use platform details shown on page 3 and as shown on Drawing H-14-102407, SHMS(E+) Platform Assembly
