Problems and mistakes in cryogenic measurement

Jack Ekin
National Institute of Standards and Technology, Boulder, CO 80305 USA

Failures are sometimes more instructive (and entertaining)
than successes. Usually these do not get publicized, and,
as a result, they are often repeated. In that spirit, I
share a few of my prime examples, as well as the lessons
learned. Based on the text Experimental Techniques for Low
Temperature Measurements,¹ a brief overview is given of how
(and how not) to design a measurement cryostat, as well a
few of the obvious (and less obvious) experimental pitfalls
to be avoided. Materials selection is one of the more
critical elements, and in that vein, a free website
(www.ResearchMeasurements.com) has been created with over
ten thousand annotated cryogenic materials data entries that
can help simplify this task.
