Hi, bidding on a working Spicer SC12 EMI Cancellation System. This is a complete working set. Has controller, AC sensor, and all X, Y, and Z cancellation coils. Complete and ready to go. To be used on scanning electron microscope SEM, Transmission Electron Microscope TEM and Focused Ion Beam systems FIB. Link to the Manual: http://www.mhzelectronics.com/ebay/manuals/spicer_consulting_sc12_magnetic_field_cancelling_system_manual.pdf Key Features: •AC Field Cancelling •50 milligaus Pk-Pk Range •0.5 Hz - 5 kHz AC Bandwidth •50 X Field Improvement Typically •Full 3 Axis System •DC Cancelling Option •Measures magnetic fields •1 microgauss resolution Description: The SC12 was introduced in 1996 to replace the original Spicer Consulting SC07 System. Hundreds of SC12 systems are in use, world-wide, protecting electron and focussed ion beam tools against magnetic fields. It is now being withdrawn in favour of the new SC22 cancelling system. This basic AC cancelling installation comprises the Magnetic Field Control Unit, the X,Y and Z multicore cables and the magnetic field sensor. The system works by superimposing a cancelling field of the correct amplitude, phase and direction to null out the problem field. The SC12 magnetic field control unit contains amplifiers which drive currents through the cables to generate the cancelling field. The magnetic field sensor measures the field on X,Y & Z orthogonal axes in real time, then the measured signals are amplified and fed back in anti-phase to the power amplifiers. Hence the system is closed loop and the negative feedback nulls the field at the sensor location. The SC12 includes an accurate magnetic field measuring capability with a 3.5 digit panel meter for display. The real time measured fields are also available as analog voltage levels for oscilloscope or chart recorder display. The basic SC12 can measure the true RMS amplitude of AC fields. When a DC sensor is added, the system can also measure incremental DC fields. The panel meter can be switched to display any of the axes.
