Helium Monaxial Vapor-Cooled Current Leads
Standard Monaxial Vapor-Cooled Current Leads suit both persistent mode and swept-field magnet operation
Special mounting flanges available
Custom designs and non-standard current ratings available upon request
Cryomagnetics manufactures efficient introduction of high currents into the liquid helium environment through vapor-cooled leads that utilize helium off-gas for cooling. This design minimizes system heat load and reduces helium loss rates. These leads represent a solid choice for researchers using both operational modes, with an alternative product available for persistent-mode-focused applications.
Dimensional specifications for the 10 standard configurations (M50 through M1000).
