Mag-NetX® Active Magnetic Field Cancellation

  • Overview +

    Building upon our advanced control systems engineering and technology to actively sense and cancel building floor vibrations, we now offer Mag-NetX®, an innovative system providing active compensation of magnetic field fluctuations.

    Designed both for point-of-use and OEM applications, Mag-NetX is ideal for scanning and transmission electron microscopes, electron beam lithography systems, ion beam instruments, and any tools that incorporate a charged beam. Combining Mag-NetX with TMC’s advanced vibration isolation systems, we can provide the ultimate control of vibration and magnetic fields.

  • The Mag-NetX® Advantage +

    Analog Controller with Digital interface Analog control of Helmolz-type coils results in more precise real-time cancellation. Digital panel provides simple LCD read-out or PC-based Graphical User Interface (GUI) to the user.

    Flexibility for On-site Tuning Auto-tuning at start up for typical environments and applications, or adjustable on-site tuning for more challenging environments.

    Real-time monitoring Continuous monitoring with measured fields displayed via the PC-based GUI allows for fine tuning even without relying on microscope image.

  • Performance +

  • Helmholtz Coil Configurations +

    • Column-Mounted Helmholtz Coils
      • Column-mounted Helmholtz Coils are readily adapted to SEM columns but impractical for TEMs.
    • Floor-Mounted Helmholtz Coils
      • Floor-mounted Helmholtz Coils may be used for both SEMs and TEMs.
    • Helmholtz Coils on a Leg Frame
      • Helmholtz Coils may be mounted on a TMC leg frame.
    • Wall-Mounted Helmholtz Coils for Ceiling
      • Wall-mounted coils are a practical alternative to column and floor-mounted coils for TEMS and SEMs installed near the center of a room.
    • Wall-Mounted Helmholtz Coils for floor
      • Wall-mounted coils are a practical alternative to column and floor-mounted coils for TEMS and SEMs installed near the center of a room.
