From October 23 to 25 2024, we attended the 4th International Workshop on Cooling Systems for HTS Applications (IWC-HTS) in Matsue, Shimane Prefecture, Japan. Between fascinating talks and poster sessions some of Japan's wonderful culture and cuisine could be experienced during a multi-stop excursion and the conference dinner. Also, our doctoral researcher Friederike Boehm won the "Best Student Presentation Award.

On July 2, 2024, our yearly excursion to the MiRO refinery took place again in the frame of the ‚Industrial Gases Processing Course' (Refrigeration B). Our students got a great insight into the work life of process engineers in the largest refinery in Germany, discussing also challenges and prospects of the energy transition.

Current Research Topics
The Einstein Telescope (ET) is a proposed underground infrastructure to host a third-generation, gravitational-wave observatory. It builds on the success of current, second-generation laser-interferometric detectors Advanced Virgo and Advanced LIGO, whose breakthrough discoveries of merging black holes and neutron stars over the past 5 years have ushered scientists into the new era of gravitational-wave astronomy.

Refrigeration processes operated with wide-boiling refrigerant mixtures known as cryogenic mixed-refrigerant cycles (CMRC) are an attractive technology for providing cooling capacity in the temperature range between 80 K and 200 K.
Details
The properties of cryogenic fluid mixtures are of fundamental importance for the development and optimisation of closed-cycle cryogenic cooling systems needed for applications of high-temperature superconductivity (HTS) and for the liquefaction or re-liquefaction of low-boiling fluids.
