Negative Ion Source Development for Fusion Application (invited) [PDF]

open access: yes, 2010
Giant negative ion sources, producing high-current of several tens amps with high energy of several hundreds keV to 1 MeV, are required for a neutral beam injector(NBI) in a fusion device.

Overview of the design of the ITER heating neutral beam injectors

open access: yesNew Journal of Physics, 2017
The heating neutral beam injectors (HNBs) of ITER are designed to deliver 16.7 MW of 1 MeV D ^0 or 0.87 MeV H ^0 to the ITER plasma for up to 3600 s. They will be the most powerful neutral beam (NB) injectors ever, delivering higher energy NBs to the ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

2D accelerator design for SITEX negative ion source [PDF]

open access: yes, 1983
Solving the Poisson-Vlasov equations where the magnetic field, B, is assumed constant, we optimize the optical system of a SITEX negative ion source in infinite slot geometry.

Integrated Modeling of the Beam Formation and Extraction in the Linac4 Hydrogen Negative Ion Source [PDF]

open access: yes, 2018
In order to make the predictive simulation tools for the extracted beam current and emittance in the Linac4 H− ion source, we have launched the development of the integrated model for the H− ion beam formation and extraction process.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Negative ion sources for neutral beam systems [PDF]

open access: yesJournal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1983
Neutral beams to heat the plasmas of controlled fusion experiments are generated by neutralizing the charge of positive ions after they have been focused and accelerated. The efficiency of this system decreases with ion velocity and for D+ the system is practical only at ion energies of less than about 150 keV,which is less than the energies expected ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Improving a gas ion source for C-14 AMS [PDF]

open access: yes, 2013
For more than 4 years, gaseous samples of 1-50 mu g carbon have been routinely measured with the gas ion source of the small AMS (Accelerator Mass Spectrometer) facility MICADAS (Mini CArbon DAting System) at ETH Zurich. The applied measurement technique

100 seconds and megawatt negative ion beam accelerations at the CRAFT NNBI test facility

open access: yesNuclear Fusion
A promising negative-ion-based neutral beam injection (NNBI) system should achieve high energy, high power and long pulse simultaneously for the plasma heating and current drive in the large-scale fusion devices. A NNBI test facility has been constructed
