Highly charged ions (HCIs) have opened up various research frontiers in fundamental physics, such as recent proposals for atomic clocks based on heavy HCIs with many electrons. This paper demonstrates a laser spectroscopic method using an electron beam ion trap plasma with a quasi-Zeeman-free low magnetic field to deepen understanding of their hyperfine structure.
