Members of the Institute for Micro- and Nanoelectronic Systems have presented an analytical model of a microwave SQUID multiplexer in the journal Superconductor Science and Technology. This model enables a significantly improved description of such quantum interference detectors compared to previously existing models. Further information and access to the publication can be found here.

Members of the Institute for Micro- and Nanoelectronic Systems, in collaboration with colleagues from Heidelberg University, have presented a new multiplexing method for large-scale cryogenic microcalorimeter arrays in the renowned journal Applied Physics Letters. The article was selected by the editors as a "Featured Article" and appeared on the cover of the journal's April 18, 2022 issue.

Radionuclide metrology relies on well-established measurement techniques that have been used and refined over decades. For some nuclides, lower achievable uncertainties are possible than for others. Bridging this knowledge gap is a key objective. As part of the EMPIR project "PrimA-LTD", the IMS is contributing to the development of new primary techniques for activity standardization based on magnetic calorimeters. By combining high-resolution spectrometry of radioactive decays with advanced new theoretical calculations of spectral shapes, the project aims to improve our understanding of fundamental decay data.
