CryoMagn 1-40-12 Print
  • Cryostat with superconducting magnet up to 12 Tesla at 4.2 K

The cryostat CryoMagn 1-40-12 with superconducting magnet designed for the studies of the superconductivity, the quantum Hall effect, magneto-optics investigations in magnetic field up to 12 T at 4.2 K. The cryostat allows the use of the variable temperature inserts for temperature region 0.3 – 273 K.

The design suggests location of the superconducting magnet in a completely welded liquid helium reservoir. Small opening for variable temperature inserts is compatible with the magnet bore. This minimizes the heat flow from the top flange to the helium reservoir. The copper shield attached to the bottom of the nitrogen reservoir and cooled by liquid nitrogen hangs over the cryostat to its bottom. The shielding reduces the helium boil-off and optimizes the consumption of cryogenic liquids. The built-in liquid helium level gauge and removable liquid helium transfer line provide the helium level monitoring and filling services.

The highly reliable superconducting solenoid with attachable copper or HTSC current leads is built by multifilament wire based on NbTi and Nb3Sn superconductors. The resistor/diode protection circuit secures the safety use of the superconducting solenoid. As an option, we supply a superconducting switch to maintain the superconducting short-cut regime and the electrical power supply for solenoid.
