Welcome to the IMS
The Institute of Micro- and Nanoelectronic Systems (IMS) is an institute of the KIT Faculty of Electrical Engineering and Information Technology of the Division III "Mechanical and Electrical Engineering" at the Karlsruhe Institute of Technology (KIT). The scientific focus of the IMS is on the development of novel quantum-technological detector and sensor systems with ultra-high time and energy resolution whose performance is far beyond the limits of conventional electronics. Our vision is to anchor these innovative systems as a universal tool in the natural sciences, life sciences, and industry and thus to contribute to the solution of present and future challenges in research and industry. In teaching, the IMS actively participates in the basic education of the faculty's students. In addition, the Master's program teaches the relevant basics for the research focus of the institute. In particular, students are given the opportunity to participate in the development of an exciting and rapidly developing field of research or to contribute their own ideas for the technology of the future by means of case studies, internships, seminars and academic theses.

Talks
The workshop “Cryoelectronic Devices” (KRYO) has been bringing together scientists and engineers from Germany for more than 40 years to discuss the latest developments in the fields of superconducting electronics and devices, cryogenic detectors, cryogenics, and related applications. This year’s workshop was hosted by the Institute for Micro- and Nanoelectronic Systems (IMS) in Bad Herrenalb. Initially, 56 participants received four introductory lectures from renowned representatives of the field, followed by three days of intensive discussions on 16 presentations and 16 poster contributions from the participants. Social hours in the evenings rounded off the workshop. All participants agreed that the workshop was a great success and look forward to coming together again next year.
Six doctoral students from KIT express their heartfelt thanks to the KIT Center KCETA for financial support, which enabled them to participate in the workshop as young scientists.
In strong collaboration with several partners, researchers from the Institute of Micro- and Nanoelectronic Systems (IMS) have presented a magnetic microcalorimeter with integrated SQUID readout that has set a new world record for the resolution of an energy-dispersive detector in the X-ray range up to 10keV. The corresponding paper was published in Applied Physics Letters and was awarded as "Editor's Pick" by the editors. Further information and the corresponding open access publication can be found here.

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.
Forschende des Instituts für Mikro- und Nanoelektronische Systeme haben im „Journal of Applied Physics“ eine Software präsentiert, mit der Mikrowellen-SQUID-Multiplexer sehr detailliert numerisch simuliert werden können. Die Software erlaubt eine systematische Optimierung und theoretische Untersuchung dieser Bauteile, wie sie mit rein analytischen Methoden nicht möglich ist.

Die Radionuklidmetrologie stützt sich auf bewährte Messverfahren, die seit Jahrzehnten eingesetzt und verbessert wurden. Einige Nuklide weisen hierbei eine bessere erreichbare Unsicherheit als andere Nuklide auf. Diese Wissenslücke gilt es zu schließen. Im Rahmen des EMPIR-Projekts „PrimA-LTD“ beteiligt sich das IMS an der Entwicklung neuer, auf magnetischen Kalorimetern basierenden Primärtechniken für die Aktivitätsstandardisierung. Die Kombination von hochauflösender Spektrometrie für radioaktive Zerfälle mit ausgefeilten neuen theoretischen Berechnungen der Spektralform wird hierbei das Wissen über die grundlegenden Zerfallsdaten verbessern.
