Biogeochemical tools for characterizing organic carbon in inland aquatic ecosystems

Limnology and Oceanography Letters, 2018
Integration of inland waters into regional and global carbon (C) budgets requires a comprehensive understanding of factors regulating organic carbon (OC) delivery and in situ processing.

Investigation of spatial distribution characteristics of emission intensity in detachment on the divertor simulator TPDsheet-ICR

Nuclear Materials and Energy
For the first time, we have revealed the spatial structure of a detached plasma with electron–ion recombination (EIR) and molecular-activated recombination (MAR) in response to changes in ion temperature (Ti) and gas pressure.

Gyrokinetic profile prediction and validation of a negative triangularity plasma in ASDEX Upgrade

Nuclear Fusion
In this work, gyrokinetic simulations are performed with the CGYRO code (Candy et al 2016 J. Comput. Phys. 324 73–93) for a negative triangularity H-mode plasma in ASDEX Upgrade, and compared with experimental measurements.

Lake dissolved organic matters seasonal variations is a main driver of N2O emission: In molecular insights by using FT-ICR MS

Water Research X
Anthropogenic activities have introduced substantial quantities of carbon and nitrogen into aquatic system, which are hotspots for nitrous oxide emissions and play multiple roles in the global biogeochemical cycle. We characterized the seasonal variation

Velocity-space tomography of MeV-range fast-ion distributions in JET using wave–particle interaction priors

Nuclear Fusion
The fast-ion distribution function in fusion plasmas can only be measured indirectly by solving an ill-posed inverse problem. The inversion being ill-posed necessitates regularisation of the problem to ensure that the reconstruction of the fast-ion ...

Propagation of ion cyclotron emission in the DIII-D tokamak

Physics of Plasmas
Experiments in L- and H-mode plasmas performed on the DIII-D tokamak explored ion cyclotron emission (ICE) propagation via the recently upgraded ICE diagnostic. The distance between the plasma and the outer wall was scanned to alter the evanescent region, which was seen to impact the detection of runaway electron-driven whistler modes in a comparable ...

Characteristic Kα emission of electron cyclotron resonance ion source plasmas

, 2018
This thesis presents the results of an investigation of the volumetric Kα emission rate/inner shell ionization rate from an Electron Cyclotron Resonance Ion Source (ECRIS) plasma tuned predominantly for high charge state ion production. The experimental work include four complimentary studies covering the influence of a parametric sweep of the four ...

Does SN 1987A contain a rapidly vibrating neutron star [PDF]

If the recently reported 0.5 ms-period pulsed optical signal from the direction of Supernova 1987A originated in a young neutron star, its interpretation as a rotational period has difficulties. The surface magnetic field would have to be much lower than
