Spectroscopic measurements of highly charged ions produced in an electron beam ion trap for atomic, nuclear and astrophysics applications

ORAL · Invited

Abstract

Using the electron beam ion trap (EBIT) facilities at the National Institute of Standards and Technology (NIST), the Center for Astrophysics (CfA) | Harvard & Smithsonian, and TRIUMF, we perform spectroscopic experiments with highly charged ions (HCI). HCI are interesting due to their exotic properties compared to neutral atoms, such as the enhanced overlap of their electronic wavefunctions with the nucleus. These ions also mimic the conditions of solar corona and plasmas found in the interstellar and intergalactic medium, and fusion plasmas. Measurements of the atomic transitions in HCI are thus relevant to astronomy, atomic, nuclear, and fusion physics. I present an overview of some of our ongoing spectroscopic efforts with EBITs through multiple collaborations. Some of these include line identification measurements, probing the nuclear charge radius, and extending EBIT measurements into the IR region.
