Overview

The magnetic field cancellation system from Spicer provides unmatched protection against AC and DC fields for high resolution electron microscopes. The Spicer System is designed to integrate seamlessly around an electron microscope, offering maintenance-free EMI shielding for any lab or research facility. Electron microscopy users often choose the Spicer System because it is a cost-effective solution that can vastly improve the imaging of most electron microscopes operating in environments with disruptive EMI noise.


Product Highlights

There are two models available (SC-22 and SC-24) for different isolation requirements. The SC-22 is intended for cancelling AC fields only, while the SC24 is intended for cancelling AC and DC fields. Both systems offer protection against fluctuations in magnetic fields caused by:

  • Subways
  • Electrical Distribution Equipment
  • Elevators
  • Moving Vehicles

SC22 Product Highlights

SC22 AC Sensor
SC22 AC Sensor
  • Low cost, high performance system
  • Automated set up with an intelligent user interface
  • Cancels AC fields from 2.5 Hz to 5 kHz, 50 x field improvement at 60 Hz
  • Full 3 axis (X, Y, Z) system, Up to 60 mG (6.0 μT) pk-pk range
  • Adapts to field changes within 100 μs
  • Supports dual sensors for TEMs and high gradient fields

SC24 Product Highlights

SC24 DC and AC Sensor
SC24 DC and AC Sensor
  • Use AC sensors for cancelling 50/ 60 Hz AC line fields or DC sensors for cancelling tram and train DC fields and 50/60Hz
  • Simultaneous AC & DC field display with choice of Tesla or Gauss units
  • Mixes dual sensors to create virtual sensor “inside” the EM column
  • Adapts to field changes within 100 μs
  • Touch screen intelligent user interface with automatic setup and DC reset
  • Ethernet and USB ports for remote operation and monitoring
  • Built-in test field generator

Applications

The Spicer System broadens the available installation locations for electron microscopes by allowing them to be placed in locations where varying high magnetic fields are present. As a result, they can be installed at sites previously rejected due to magnetic field interference.

Common applications include:

  • Scanning Electron Microscopes
  • Transmission Electron Microscopes
  • MRI Machines
  • And more!
