Temperature Distribution in Liquid and Vapor Phases of Helium in Cylindrical Dewars
The temperature variation in the liquid and vapor phases of helium contained in a dewar vessel has been measured along the axis and side of the dewar. Such information is helpful in the evaluation of data in cryogenic experiments in which a significant portion of the apparatus lies in a temperature gradient. The work described below was prompted by this consideration. However, the unexpected nature of the temperature variation led to a more detailed investigation.
