Supervarimag superconducting magnet system SVM series

      standard SuperVariMag The system provides 6 to 9 T（ Niobium titanium coil ） and 10 to 12 T（ Niobium tin coil ） The magnetic field , The diameter is 1.0 Inches to 1.5 Inch sample tube , And one. 20 L The open neck helium tank with effective capacity is in a steam shielded super insulated Dewar .

      Standard configuration

      Although standard systems provide vertical magnetic fields and split pairs of coils , However, the two coil or three coil configuration also provides various field strengths for horizontal field direction or rotating vector field .

      SuperVariMag The system can also provide a larger helium capacity Dewar , Among them “ abdomen ” Increased helium capacity is provided above the magnet . They can also be provided at ultra-low losses (ULL) Low temperature thermostat , The cryostat provides 4 To 5 l / Static loss rate of days , Magnets and variable temperature inserts are in place . High efficiency systems usually use low current magnet designs and low temperature thermostats , The cryogenic thermostat is equipped with a nitrogen reservoir 、 Super insulation and additional radiation shielding between helium and nitrogen reservoirs , To provide ultimate efficiency in the top loading system .

      When needed ,Lake Shore Also provide 9 T/11 T to 12 T Magnets and Lambda Point the cooler (LPR), For operation under high magnetic field , The reservoir is under atmospheric pressure .SuperVariMag The system provides a cost-effective system , The static holding time is from 2 Day to 10 Different days , And in 1 There is 0.5% and 0.1% Field uniformity . Larger sample tubes （3 To 4 Inch outside diameter ） And higher field uniformity （0.01 % Or better than 1 A sphere of centimeter diameter ） And special field profiles are available . Use SuperVariMag The system can easily carry out critical current 、 Resistivity 、 specific heat 、 Hall effect and other non optical experiments . By adding an appropriate gradient 、 Modulation and pickup coil ,SuperVariMag The system is easily applicable to Faraday balance induction measurement .

      SuperVariMag Series can be combined with optional independent magnet bracket and wiring system , This allows the magnet to be used with multiple inserts . In this configuration , It can be introduced and removed without disturbing the magnet SVT plug-in unit .

      standard SuperVariMag System specifications

      Other configuration

      be used for He4 and He-3 Sample probe with precision rotator of low temperature thermostat

      For applications that require rotating the sample plane relative to the vertical magnetic field ,Janis There are also two options . The first provides continuous rotation of the sample plane , The second provides precise rotation , Usually as high as 100°. The precision rotator is also suitable for inserts with samples in vacuum . These sample rotators can be used in non optical systems and optical systems .

 

      special SuperVariMag System

      SuperVariTemp The plug-in can also be used in applications that require samples to be in high vacuum or ultra-high vacuum . Special compact plug-ins （ With or without superconducting magnet ） It can also be installed in standard or special liquid helium storage Dewar bottles , But the sample space is limited .

      9TM-SVM-20 High efficiency superconducting magnet system

      Lake Shore I'm glad to provide ultra-low loss liquid helium cryostat , The low temperature thermostat is equipped with 9 T Superconducting magnet and two top loading inserts （He-3 and He-4）. Both plug-ins are equipped with precision rotary tables , It allows you to rotate the sample holder around a horizontal axis perpendicular to the direction of the vertical magnetic field . The rotation angle can 0.2° Make changes for increments , The sample rotator is shown on He-3 and He-4 In the display photo of the blade . The sample bar is removable , There is no need to preheat the cryostat or magnet , Samples can be changed quickly .
