Advanced methods in fourier transform ion cyclotron resonance mass spectrometry [PDF]

Mass spectrometry (MS) is a powerful analytical technique used to characterize various compounds by measuring the mass-to-charge ratio (m/z). Among different types of mass analyzers, Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR ...

Altitude Dependence of Quasi‐Static Potential Drop: The Effect of Ionospheric Protons

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Using an improved kinetic model that incorporates cold ionospheric protons and oxygen ions, we investigate the factors controlling the altitude range of the auroral acceleration region (AAR). In this model, parallel electric fields are generated via Dispersive Alfven Wave‐ Modified electron Acoustic Wave (DAW‐MEAW) coupling and sustained by ...

Core plasma ion cyclotron emission driven by fusion-born ions [PDF]

, 2019
Ion cyclotron emission (ICE) signals whose spectral peaks match the fundamental cyclotron frequencies of hydrogen and tritium in the plasma core, near the magnetic axis, are observed in ASDEX Upgrade deuterium plasmas.

Simulations of ion cyclotron emission from highly energetic fusion-born protons in aneutronic deuterium-helium-3 plasmas

Nuclear Fusion
Studies of future aneutronic fusion plasmas, such as those comprising deuterium and helium-3 (D– $^3\mathrm{He}$    $\rightarrow \mathrm{^4He}+p$ ), may not be able to exploit neutron-based diagnostics for direct measurement of fusion reactivity.

Molecular Evidence for the Atmospheric Transformation of Trash Burning Aerosol Into Organonitrate‐ and Organosulfate‐Rich Haze: A Case Study From the Eastern Indo‐Gangetic Plain

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Open burning of solid waste is projected to contribute up to 29% of global anthropogenic PM2.5 emissions, yet its role in secondary aerosol formation remains largely absent from current assessments. Using 21‐T Fourier transform‐ion cyclotron resonance mass spectrometry, we show that fresh trash burning organic aerosol (tbOA) in the Indo ...

Spatiotemporal structure of edge harmonic oscillation and its role in ELM-free QH-mode at KSTAR

Nuclear Fusion
In Quiescent H-mode (QH-mode), edge-localized modes (ELMs) are naturally replaced by a low- $n$ edge harmonic oscillation (EHO), yet the self-regulating transport mechanism driven by the EHO remains insufficiently understood.

Velocity-space tomography of an MeV fast-ion tail generated by three-ion scheme ICRF heating at JET

Nuclear Fusion
Recently-developed methods are used successfully to reconstruct the two-dimensional velocity-space distribution of the energetic minority MeV ion tail created by heating in the ion cyclotron range of frequencies (ICRFs) in the D–D $ _{\mathrm{NBI}}$ – ^3
