Polarization measurements of the $2 s$ -- $2 p_{3/2}$ VUV transition in N $^{4 +}$ excited by electron collisions

Nobuyuki Nakamura, Ryohko Ishikawa, Motoshi Goto

We present the linear polarization of the $2 s$ -- $2 p_{3/2}$ transition in Li-like N $^{4 +}$ 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…
