[Basic Knowledge about Cryopumps 4 ] | ULVAC CRYOGENICS INC

2-2.Pumping Characteristic for Argon and Nitrogen (Condensable Gas) A group of gases such as N 2 、Ar、CO、O 2 and other gases of similar molecular weight are condensed and pumped at 20K or below, therefore they are not condensed on 80K baffle and shield. In general, the limit temperature that gases can be pumped by condensation is 20K.

[Basic Knowledge about Cryopumps 1 ] | ULVAC CRYOGENICS …

As you see in Fig.1, the vapor pressure of water vapor becomes below 10-8 Pa at temperature of below 130K, and thus water vapor is pumped as a result of condensation on the 80K baffle and 80K shield. The next group of gases, nitrogen, oxygen, argon, and other gases of similar molecular weight are pumped at the exposed surface of 15K cryopanel(1) at the second stage, which is kept below 20K.
