A new type of cryostat is described which enables tensile plastic deformation of copper alloys at liquid helium temperatures and measurements of thermal conductivity to be made without allowing the samples to age at temperatures above the liquid helium range. The cryostat has also been adapted for r

The dielectric strength of coaxial cylindrical gaps in vacuum, gaseous helium at low temperature or liquid helium has been investigated under d.c. stresses in the presence of transverse magnetic field. Experimental results show that the dielectric strength in vacuum is lowered drastically by the app
