Figure 3
Gas flow in the cryo-stage cooling system. Helium cryogen gas first passes through an intermediate-temperature heat exchanger where it is cooled to ∼120 K, before passing through a low-temperature exchanger where it is further cooled to the desired specimen temperature. The 77 K nitrogen-cooling loop is shown relative to the helium gas flow and the two heat exchangers.
