Planck’s cooling system (at 4 degrees Kelvin)
May 26, 2009
To achieve the mission goals, the Planck instruments - the Low Frequency Instrument (LFI) and the High Frequency Instrument (HFI) - will operate at a few degrees above absolute zero. To achieve this, a series of cooling stages are required.
The picture shows the second cooling stage which brings the temperature inside HFI down to 4K.
