Heat transfer is an essential contribution to the overall performance of cryogenic systems. The influence of the interface thermal contact is rising with decreasing temperature. We are studying the thermal performance of copper – indium – sapphire sandwich setup to achieve maximum thermal contact at temperatures well below 300 mK. Steady-state measurements with indium in normal conducting and...
The talk gives an overview of current experimental and theoretical work on cryogenic safety in the frame of a collaboration between KIT and CERN. In addition, the activities to organize a working group at the European Committee for Standardization (CEN) is presented, which will work on a European standard on safety of liquid helium cryostats.
