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 ...

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.

Mechanism of enhanced ion temperature by impurity seeding in EAST H-mode plasma

Nuclear Fusion, 2023
Ion temperature ( T _i ) profiles are commonly observed to increase in peaking, leading to higher central T _i , after impurity seeding in the EAST H-mode plasma. Argon can be more efficient at raising T _i than neon.

Observations of xenon spectra on the EAST x-ray crystal spectrometer for high-temperature plasma diagnostics

Nuclear Fusion, 2023
The Xe ^44+ 2.7203 Å line, which has been proposed as one of the diagnostic lines for the x-ray imaging crystal spectrometer on ITER, is observed on the EAST tokamak together with its several satellite lines. The observations are made under high electron

Periodicities in the Io plasma torus [PDF]

, 1995
We present a 6-month baseline of spatially resolved measurements of the Io plasma torus intensity and perpendicular ion temperature which we use to determine the periodicities of the torus during this time.

Low-temperature ion-beam mixing in metals [PDF]

Physical Review B, 1988
A systematic study of ion-beam mixing of tracer impurities in thin metal films at low temperatures has been conducted. We have investigated the dependence of ion mixing on two matrix properties: atomic mass and cohesive energy. We have also studied the dependence of ion mixing on tracer impurity properties: its heat of mixing with the matrix and its ...

Influence of the Ion Mass in the Radial to Orbital Transition in Weakly Collisional Low-Pressure Plasmas Using Cylindrical Langmuir Probes

Applied Sciences, 2020
This paper presents an experimentally observed transition from the validity of the radial theories to the validity of the orbital theories that model the ion current collected by a cylindrical Langmuir probe immersed in low-pressure, low-temperature ...

Thermalization and temperature distribution in a driven ion chain [PDF]

, 2010
We study thermalization and non-equilibrium dynamics in a dissipative quantum many-body system -- a chain of ions with two points of the chain driven by thermal bath under different temperature.
