Researchers at the Institute of Micro- and Nanoelectronic Systems have recently presented a novel concept for a superconducting microcalorimeter that is particularly suitable for high-resolution soft X-ray spectroscopy. The corresponding work was published in Applied Physics Letter. Further information and the actual publication can be found here.

High-resolution X-ray spectroscopy at modern synchrotron light sources is an indispensable tool for many fields of science. Existing X-ray spectrometers, however, provide either excellent resolution at low efficiency or moderate resolution at high efficiency. Within the project "QUASY - Quantum Sensor Platform for Synchrotron X-ray Spectroscopy", funded by the EXU initiative KIT Future Fields, the KIT institutes IMS, IPS, and INE therefore intend to install a quantum sensor array as demonstrator at the KIT Light Source to prove that high efficiency and excellent energy resolution can be achieved at the same time. The successful completion of this project will subsequently pave the way for the future application of highly efficient and ultrahigh-resolution quantum sensors in X-ray spectroscopy at modern synchrotron light sources.

Researchers at the Institute for Micro- and Nanoelectronic Systems have presented a software tool in the Journal of Applied Physics that enables highly detailed numerical simulations of microwave SQUID multiplexers. This software facilitates systematic optimization and theoretical analysis of these components, which would not be feasible using purely analytical methods

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.

Together with the Institute of Technical Physics (ITEP), the Institute of Micro- and Nanoelectronic Systems (IMS) will offer the new specialisation 26 "Applied Superconductors Engineering" from the summer semester 2021. Students will be trained to become experts in this promising field of electrical engineering and information technology. The specialization can be studied in German as well as in English.

Together with the Institute for High Frequency Electronics (IHE), the Institute for Micro- and Nanoelectronic Systems (IMS) has revised the specialization 15 and expanded it to include elements of current topics in micro-, nano- and quantum electronics. In this way, students are to receive sound knowledge in an industrially enormously important area.
