✦ Synopsis

Simple helium dewars have been constructed using gas-cooled radiation shie/ds and multilayer aluminized plastic insulation. They will retain one litre of liquid for up to 40 hours The shields may be made mostly non-conducting so the dewar can be used with ultrasensitive superconducting magnetometers. For most other applications thin sheet metal such as copper or aluminium is suitable for the shield& Portable helium dewars for use with superconducting magnetometers
