A lot of our research is performed at temperatures close to absolute zero, among other reasons because this increases the sensitivity of the measurements. 

111 years ago, Heike Kamerlingh Onnis liquified helium for the first time, a tour the force that netted him the Nobel prize. It took a laboratory of a size rarely seen. Now, ultracold helium has become a commodity for physics research. In Wolfgang Löffler's lab, it is ready at hand thanks to a coffee…

To be able to measure small forces or small deviations from Boltzmann, the external vibrations at the resonance frequency must be very low. To achieve this, we have developed a very soft vibration isolation system and combine it with several other measures to reduce vibrations in our dilution refrigerators.…

The Cryogenics Department has a liquid helium production unit and an automatic liquid nitrogen filling plant.
