DRASTIC REDUCTION OF WARM-UP RATE WITHIN A DEWAR SYSTEM BY HELIUM DESORPTION.

Abstract

A method is described whereby the time rate of temperature change is drastically reduced within a glass double-dewar system over the interval 4.2 to 77K. The problem of reducing the rate of change is solved successfully by inserting a small amount of activated charcoal in the inner dewar. The explanation of why it succeeds is presented and results are given showing the drastic reduction of warm-up rate for various amounts of charcoal. Some advantages of such a simple scheme are listed. (Author)
