Ion cyclotron emission from energetic ion populations in fusion plasmas [PDF]

, 2019
In this thesis I present particle in cell (PIC) simulations of ion cyclotron emission (ICE). ICE comprises suprathermal radiation in the ion cyclotron frequency range, whose spectrum peaks at successive local cyclotron harmonics of the emitting energetic ion population.

Keeping It Native: Non‐Denaturing Approaches to Top‐Down Protein Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics and top‐down mass spectrometry approaches provide direct characterization of proteoforms; the specific molecular forms of proteins, including post‐translational modifications, truncations, alternative splicing, and sequence variants.

Dependence of ion-cyclotron range of frequencies instabilities on species mix and fast-ion distribution: I. Stability

Nuclear Fusion
Ion cyclotron emission (ICE) driven by fast ions has the potential to be a reactor relevant diagnostic of confined and escaping fast ions; moreover, controlled experiments in magnetic fusion devices can shed light on similar magnetospheric instabilities ...

Edge radiated temperature fluctuations across confinement regime transitions in favorable and unfavorable drift configurations at ASDEX Upgrade

Nuclear Fusion, 2023
The physics behind the difference in heating power threshold for the low to high confinement (L–H) transition between favorable ion $B \times \nabla B$ drift (toward active X -point) and unfavorable ion $B \times \nabla B$ drift (away from active X ...

Large‐Scale Applications of Plasma Technologies: Progresses and Challenges

High Voltage, EarlyView.
ABSTRACT Plasma technologies convert electrical power into energetic electrons, ions, reactive species, radiation and heat, thereby breaking through the bottleneck of purely thermal or chemical routes and bringing impressive changes to our world. This roadmap reviews the progress and challenges of plasma technologies from a large‐scale and application ...

Eccentric Occlusal Loads Remodel the Dentoalveolar and Temporomandibular Biomechanical Unit in Rats

Journal of Oral Rehabilitation, EarlyView.
Eccentric occlusal loads remodel the dentoalveolar and temporomandibular joints in the masticatory biomechanical unit in rats. (A) Bite block as an occlusal rise (OR) on the rat maxillary first molar (green region) is shown. (B) 18F‐NaF Positron emission tomography localised regions of higher metabolic activity (higher uptake in the left condyle ...

RECENT RESULTS ON THE DISCREPANCY BETWEEN ELECTRON TEMPERATURE MEASUREMENTS IN HIGH TEMPERATURE PLASMAS IN JET

, 2009
The long standing disagreement between the central electron temperature measured by Thomson scattering and electron cyclotron emission (2nd harmonic, X-mode) in high performance plasmas observed in JET and TFTR is reexamined.

Chemoenzymatic Radiosynthesis of a Gluconate Transporter‐Targeted In Vivo Bacterial Sensor From Clinical [18F]FDG

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
An efficient radiosynthesis of fluorine‐18 labeled gluconic acid ([18F]FGA) was developed using two readily available materials, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose ([18F]FDG) and glucose oxidase. [18F]FGA is highly specific for bacterial gluconate metabolism mediated by gluconate permease (GntP) and gluconate kinase (GntK), with rapid clearance, low off ...

The consequences of tritium mix for simulated ion cyclotron emission spectra from deuterium-tritium plasmas

Nuclear Fusion
Measurements of ion cyclotron emission (ICE) are obtained from most large magnetically confined fusion plasma experiments, and may be used in future to quantify properties of the fusion-born alpha-particle population in deuterium-tritium (DT) plasmas in ...
