Magnet Support Assemblies
. The assemblies typically include thermal radiation baffles, helium vapor-cooled current leads with bus bars, helium fill and vent ports, a quench relief valve and a 19-pin electrical feedthrough. Access is provided through the center of the assembly for insertion of the user’s experimental apparatus.
Lambda plates are available to allow the user to operate the superconducting magnet below 4.2K. The lambda plate is capable of maintaining a magnet at 2.2K while maintaining atmospheric pressure in the dewar. Frequently one can even refill the dewar with 4.2K helium without disturbing the 2.2K magnet. A temperature sensor (typically ruthenium oxide) is installed on each unit to provide accurate monitoring of the magnet’s bath temperature.
