Effect of edge ion temperature on the divertor tungsten sputtering in WEST
Nuclear Fusion, 2023 The influence of upstream ion temperature in the scrape-off layer (SOL) on the tungsten (W) sputtering in the divertor is studied in the WEST tokamak. For an almost constant power into the SOL, the upstream ion temperature and its ratio over the electron

Temperature estimation of a pair of trapped ions
Scientific Reports, 2022 AbstractWe apply estimation theory to a system formed by two interacting trapped ions. By using the Fisher matrix formalism, we introduce a simple scheme for estimation of the temperature of the longitudinal vibrational modes of the ions. We use the ions interaction to effectively infer the temperature of the individual ions, by optimising the ...

Effective Temperature of Ions in Traveling Wave Ion Mobility Spectrometry [PDF]
Analytical Chemistry, 2011 Traveling wave ion mobility spectrometers (TW IMS) operate at significantly higher fields than drift tube ion mobility spectrometers. Here we measured the fragmentation of the fragile p-methoxybenzylpyridinium ion inside the TW ion mobility cell of the first-generation SYNAPT HDMS spectrometer.

MAVEN‐STATIC Observations of Ion Temperature and Initial Ion Acceleration in the Martian Ionosphere
Geophysical Research Letters, 2022 Though ion escape to space is an important mechanism for atmospheric loss at Mars, the processes that accelerate ions to escape velocity have not been fully identified and quantified.

Review of the NPA Diagnostic Application at Globus-M/M2
Atoms, 2023 The application of a neutral particle analyzer (NPA) diagnostic at the Globus-M/M2 spherical tokamaks is discussed. Physical principles of the diagnostic are reviewed. Two general approaches—active and passive measurements—are described.

Building a Temperature-Sensitive Ion Channel [PDF]
Cell, 2014 The biophysical basis of temperature-sensitive ion channel gating has been a tough nut to crack. Chowdhury, et al. use a protein engineering approach to render a temperature-insensitive voltage-gated channel cold- or heat-responsive to reveal principles for temperature-gating and a plausible model for molecularly enabling this mode of environmental ...

Estimation of Ion Temperature in the Upper Ionosphere Along the Swarm Satellite Orbits
Earth and Space Science, 2021 Ion temperature is one of the key parameters that provides insight into the thermal balance of the coupled ionosphere‐thermosphere system. Together with the temperatures of neutral and electron gases, it affects physical and chemical processes and ...
