Unbalanced Mixture

Least likely, is that the mixture could be disbalanced. If the phase boundary between the $ ^3$ He/$ ^4$ He liquids is not inside of the mixing chamber, the cooling power will plummet. This will only occur if there is too much, too little of $ ^3$ He, $ ^4$ He, or both.

Perform a single shot test and collect the mixture into the dumps and close V14. Record the results of this test. If the results of this test are markedly different than expected, it may be indicative of a change in the mixture. Get help.
