Anodes of elemental carbon may be discharged in a galvanic cell, using molten carbonate electrolyte, at power densities 40-100 mW/cm2. We report cell polarization, surface area, primary particle size, and crystallization index for nine particulate samples derived from fuel oil, methane, coal, biochar, petroleum coke. At 800°C, 50-125 mA/cm2 current were measured voltage 0.8 V. Power nearly the same on scales 2.8 60 cm2 active area. Constant operation small was accompanied by constant during...
TandEM was proposed as an L-class (large) mission in response to ESA's Cosmic Vision 2015–2025 Call, and accepted for further studies, with the goal of exploring Titan Enceladus. The concept is perform situ investigations two worlds tied together by location properties, whose remarkable natures have been partly revealed ongoing Cassini–Huygens mission. These bodies still hold mysteries requiring a complete exploration using variety vehicles instruments. ambitious because its targets are most...
The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) measures linear energy transfer by Galactic Rays (GCRs) and Solar Energetic Particles (SEPs) on Lunar Reconnaissance Orbiter (LRO) Mission in a circular, polar lunar orbit. GCR fluxes remain at highest levels ever observed during space age. One largest SEP events CRaTER LRO mission occurred June 7, 2011. We compare model predictions Earth‐Moon‐Mars Environment Module (EMMREM) both dose rates from GCRs SEPs this event with results...
The nearly equatorial trajectory of the Pioneer 11 spacecraft through Saturn's high energy proton radiation belts and under main A‐B‐C rings provided a unique opportunity to study radial dependence >30 MeV intensities in terms models for secondary nucleon production by cosmic ray interactions rings, situ injection neutron beta decay, magnetospheric diffusion, absorption planetary satellites. Maximum trapped measured are compared with calculated found consistent trapping times ≈40 years...
Abstract We report on the detection of protons and potential H 2 + between Saturn's F G rings based Cassini Plasma Spectrometer (CAPS) Ion Mass (IMS) time‐of‐flight (TOF) composition measurements acquired during Saturn Orbit Insertion (SOI) outbound pass. The range in dipole L shell is 2.3 < 2.8. Initial results TOF data were presented E. C. Sittler et al. (2017). Here we present latest our analysis. During SOI pass CAPS IMS was a mode reduced post‐acceleration voltage at −6 kV instead...
During the encounter with Uranus, cosmic ray system on Voyager 2 measured significant fluxes of energetic electrons and protons in regions planets magnetosphere where these particles could be stably trapped. The radial distribution energies megaelectron volts is strongly modulated by sweeping effects ofthe three major inner satellites Miranda, Ariel, Umbriel. phase space density gradient indicates that they are diffusing radially inward from a source outer or magnetotail. Differences energy...
In this report, the Commission provides guidance for protection of people living in long-term contaminated areas resulting from either a nuclear accident or radiation emergency. The report considers effects such events on affected population. This includes pathways human exposure, types exposed populations, and characteristics exposures. Although focus is considerations, also recognises complexity post-accident situations, which cannot be managed without addressing all domains daily life,...
