A variety of applications for space
Pulse tube technology has a variety of applications for space: from Earth observation to meteorology, etc. As their mechanism has no cold moving parts, the pulse tubes are extremely reliable, with an extended useful life, without generating vibrations, and at a reduced cost.
These coolers have a temperature range of between 10 and 200 K, operating with a closed helium cycle, with series of compressions and expansions that produce cold which is stored between each expansion cycle in a porous material called a “regenerator”. The system comprises a balanced pressure oscillator and a cold finger with a coaxial pulse tube.
