Polarization measurements of the -- VUV transition in N excited by electron collisions
Nobuyuki Nakamura, Ryohko Ishikawa, Motoshi Goto
We present the linear polarization of the -- transition in Li-like N excited by electron collisions, measured at electron energies between 85 and 1000~eV. The…

A vacuum-ultraviolet spectropolarimeter for an electron beam ion trap
Nobuyuki Nakamura, Ryohko Ishikawa, Motoshi Goto
We have developed a vacuum-ultraviolet spectropolarimeter for an electron beam ion trap (EBIT) to measure the linear polarization of emission lines from multiply charged ions aroun…

Photoexcitation spectroscopy of highly charged ions for application to astronomy using a compact electron beam ion trap (EBIT) at the synchrotron radiation facility SPring-8
Leo Hirata, Yuki Amano, Moto Togawa +6
In the past few decades, X-ray astronomy satellites equipped with grating spectrometers and microcalorimeters have enabled high-resolution spectroscopic observations of astrophysic…
