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

Biological effectiveness on live cells of laser driven protons at dose rates exceeding 109 Gy/s

AIP Advances, 2012
The ultrashort duration of laser-driven multi-MeV ion bursts offers the possibility of radiobiological studies at extremely high dose rates. Employing the TARANIS Terawatt laser at Queen's University, the effect of proton irradiation at MeV-range ...

Article: Heating of beam ions by ion acoustic waves [PDF]

Annales Geophysicae, 1998
Satellite measurements show that ion beams above the auroral acceleration region are heated to hundreds of eV in a direction perpendicular to the magnetic field. We show that ion acoustic waves may be responsible for much of this heating.

Beam Emittance and Bunch Length Diagnostics for the MIR-FEL Beamline at Chiang Mai University

Particles
The generation of high-quality mid-infrared free-electron laser (MIR-FEL) radiation depends critically on precise control of electron beam parameters, including energy, energy spread, transverse emittance, bunch charge, and bunch length.
