High-resolution X-ray emission study for Xe$$^{54+}$$ on Xe collisions

Abstract

We report on an experiment conducted at the ESR storage ring aiming at the study of the X-ray emission of $$\text {Xe}^{54+}$$ Xe 54 + ions colliding with Xe atoms at a beam energy of 50 MeV/u. The radiation resulting from the ion–atom interaction was observed using a high-resolution spectrometer based on metallic–magnetic calorimeter technology. In order to benchmark the capabilities of these detectors for high-precision atomic physics experiments, we identified several transitions from H-like and He-like xenon and determined their energies. Furthermore, the 1s-Lamb shift in $$\text {Xe}^{53+}$$ Xe 53 + was estimated using the measured line energies. The results are compared with previous experimental studies and theoretical predictions.

Application of a metallic-magnetic calorimeter for high-resolution x-ray spectroscopy of Fe at an EBIT

“…In order to compensate for these effects, correction algorithms in software are necessary together with corresponding measurement procedures during the experiments. In order to develop and benchmark these methods, in the past, multiple experiment campaigns have been conducted on the campus of GSI/FAIR [22,23].…”
