Optical spectra of Fe-like Mo 16+ and Mn-like Mo 17+ ions were measured using the newly
developed low-energy electron-beam ion trap at Fudan University. The observed emission …

For the problem of excessively high divertor heat flux, active impurity seeding is an effective
method to radiate the plasma energy reaching the divertor and thus achieve the divertor …

We present experimental results of the trace argon impurity puffing in the ohmic plasmas of
Aditya-U tokamak performed to study the argon transport behaviour. Argon line emissions in …

Extreme ultraviolet (EUV) spectra emitted from iron and copper ions in a range of 8–500 Å
and molybdenum ions in a range of 8–400 Å were measured in Experimental Advanced …

Two pairs of space-resolved extreme ultraviolet (EUV) spectrometers working at 5–138 Å
with different vertical observation ranges of− 7≤ Z≤ 19 and− 18≤ Z≤ 8 cm have been …

ABSTRACT A diagnostic for extreme ultraviolet spectroscopy was fielded on the sheared-
flow-stabilized (SFS) fusion Z-pinch experiment (FuZE-Q) for the first time. The spectrometer …

One of the key challenges for future fusion research is to mitigate the high steady-state heat
load on the divertor target plates, and divertor detachment offers a promising solution. The …

After a vacuum failure in a tokamak, plasma runaway or plasma disruptions frequently occur
during plasma recovery, causing difficulties in rebuilding a well-confined collisional plasma …
