      Hello!

      My favourite part of cryogenics is that we have to work with many technologies at the same time to cool down fluids to reach very cold temperatures.

      For example I work with liquid helium at – 270 degrees! To get helium this cold we compress it to increase the pressure, then use heat exchangers and turbines similar to those in jet engines to remove energy and lower the temperature.

      Finally to keep it cold we use special insulation and vacuums to keep the fluid at a cold temperature.
