Study of astrophysical plasmas in a compact EBIT — •Moto Togawa, Steffen Kühn, and José R. Crespo López-Urrutia — Max-Planck-Institut für Kernphysik

The Heidelberg compact electron beam ion traps (HC-EBIT) use permanent magnets instead of superconducting coils, operate at room temperature, and are easily transportable. They reliably produce highly charged ions (HCI) at electron-beam energies up to 10 keV. Combining them with a high brilliance synchrotron-radiation source enables resonant fluorescence spectroscopy in the X-ray region, and precision measurements stringently benchmarking atomic structure calculations and models of astrophysical plasmas. We show how, using narrow bandwidth X-ray sources and a HC-EBIT with an off-axis electron gun (Polar-X-EBIT) specific electronic processes present in astrophysical plasmas can be separately studied.
