Universal device for thermophysical experiments in a helium Dewar flask
Description
The construction of a device for thermophysical experiments and measurement of the thermal conductivity are described. The cryostat if 39mm in diameter, designed as an insert for a helium Dewar flask. The insert is equipped with quick-diassembling low-temperature vacuum seal, constructed as a lapped taper surface connection of a stainless steel parts. An express method for measuring the thermal conductivity using this insert is described. In the temperature interval from 5 K to 13K thermal conductivities of the stainless steel 12x18H10T, of electrical steel E-310, the epoxy adhesive EG-80, silicate glue with fillers are measured 2% absolute error for the method is estimated
