A micro‐calorimeter X‐ray detector of the maXs‐30 type was used to record the X‐ray radiation from Fe ions, being produced in the S‐EBIT‐I electron beam ion trap at the site of GSI. The resulting spectra demonstrate the superior energy resolving power of micro‐calorimeter detectors compared with conventional semiconductor detectors. The experiment serves as another proof of principle for the application of calorimeters as dedicated high‐resolution X‐ray spectrometers at an ion facility. Together with the development of an improved analysis algorithm for online readout, these results present a step towards the use of maXs‐type detectors as standard instrumentation at GSI/FAIR.
