The Low Temperature Laboratory (LTL) is administered by the Department of Applied Physics. It is part of the national Otaniemi Research Infrastructure for Micro- and Nanotechnologies, OtaNano, and partner in the European Microkelvin Platform.

Facilities
The Low Temperature Laboratory has advanced sub-Kelvin refrigeration facilities: two sub-mK (unique rotating cryostat and world record stationary cryostat) and more than 10 dilution refrigerators aimed for different type of experiments.

About
Record low temperatures
Low Temperature Laboratory has produced several world records of low temperatures in about thirty years' span and still holds the record for macroscopic condensed matter systems.

The success story of Finnish low-temperature physics can be uncovered at Aalto University Archives
The Low Temperature Laboratory (LTL) of Aalto University is a significant success story of Finnish science. The laboratory was founded by the Finnish physicist Olli V. Lounasmaa (1930-2002). The Archives of Aalto University hold archival collections from first few decades of the LTL’s operation, as well as the personal archive of Lounasmaa.
