    Operation. Cryopumps are commonly cooled by compressed helium, though they may also use dry ice, liquid nitrogen, or standalone versions may include a builtin cryocooler.Baffles are often attached to the cold head to expand the surface area available for condensation, but these also increase the radiative heat uptake of the cryopump.
