Cryomagnetics' Line of Monaxial Vapor-Cooled Current Leads offer
efficient introduction of high currents into the liquid helium environment (i.e., to the superconducting magnet). This is accomplished by utilizing the helium off-gas from the system to cool the power leads. The leads minimize system heat load.
Consequently, the helium loss rate of the system is also minimized. Standard Monaxial Vapor-Cooled Current Leads are a good choice for research that involves both persistent mode and swept-field magnet operation.
Retractable current leads are available to further reduce heat load while the magnet is in persistent mode. This option is available in several current ratings. The construction of retractable versions is in two sections.
The lower section is permanently mounted inside the cryostat. The upper section can be disconnected and retracted into the cryostat neck. Liquid helium consumption is significantly reduced because the thermal path to the liquid helium bath is broken.
Standard sizes and current ratings are
listed under the Specifications Tab. Special mounting flanges are available. Contact us for current ratings not listed. For the researcher who performs the majority of his/her research with the magnet in persistent mode, please check out Duty-Cycle Optimized Current Leads.
