The advanced emission Mössbauer spectrometer, eMIL (Emission Mössbauer from Ilmenau) was built for the emission Mössbauer (eMS) collaboration at ISOLDE/CERN. The set-up is based on the emission geometry and combines on-line and off-line isotope implantation used to measure hyper-fine interactions in condensed matter materials. Using radioactive Mössbauer probes that are ion-implanted into the sample, eMIL has multiple advantages over the more common transmission or electron conversion setups. The versatility of the set-up is epitomized through five different lids: rotation, magnetic, powder, hot and cold lid. These lids can be easily interchanged, without the need for re-alignment, which makes eMIL extremely flexible during beam time. eMIL had its first successful run this year, which marked the first beam time for the Mössbauer collaboration since 2018.
