TMC Introduces Mag-NetX™ to Cancel Magnetic Field Interference

Tuesday, September 20, 2005

PEABODY, Massachusetts,Technical Manufacturing Corporation (TMC) has introduced Mag-NetX™, a magnetic field cancellation system that compensates for magnetic interference that diminishes the performance of scanning and transmission electron microscopes, electron beam lithography systems, focused ion beam instruments, and other tools that incorporate a charged beam.

Building on its expertise as a designer and manufacturer of active vibration isolation systems that cancel building floor vibrations, TMC developed Mag-NetX™ to actively compensate for magnetic field fluctuations caused by nearby machinery, elevators, power lines, and other external sources.

"Ambient floor vibration and magnetic field interference present the same challenge: How to precisely control the focus of a charged beam disturbed by external influences. And often it's not clear which source is the limiting influence," said Steve Ryan, TMC vice president, marketing. "Our state-of-the-art precision vibration isolation systems cancel floor vibration. It just makes sense to also offer our customers magnetic field cancellation to provide a complete environmental solution."

Designed for both point-of-use and OEM applications, the open cube-shaped Mag-NetX™ detects magnetic fields and sends out an equal and opposite field to cancel the interference. The system is comprised of a dedicated controller with automated calibration and self-test features, AC and DC magnetic sensor, and Helmholtz coils in a structural casing. It can be floor/wall mounted or tool mounted and sized to user-specific requirements. The system is dynamic, continuously monitoring and achieves 35-40 dB of attenuation.

TMC is a unique blend of dual core capabilities - unparalleled expertise in floor vibration control and a commitment to manufacturing using precision metal fabrication techniques. The ISO 9001-certified company's products include Stacis® piezoelectric active vibration isolation systems; Electro-Damp® pneumatic/linear motor-based active vibration isolation systems; CleanTop® optical tops and breadboards; Quiet Island® sub-floor platforms for cleanroom raised floors; laboratory tables; state-of-the-art isolators; acoustic enclosures; and OEM components.
