About NEC

National Electrostatics Corp. (NEC) is the world’s leader in the manufacture of electrostatic ion beam accelerator systems. A private, employee-owned company, NEC was incorporated in Middleton, Wisconsin in 1965.

Over the past 50 years NEC has grown to over 90 employees including electrical and mechanical engineers, ion beam system technicians, craftsmen, and other skilled workers. The NEC factory is located approximately 20 minutes from the Madison, Wisconsin airport. Our Facilities cover over 75,000 sq. ft and include both manual and CNC machine shops, a complete metal/ceramic bonding facility, vacuum components and electrical components assembly areas, as well as space for extensive testing of Pelletron accelerator systems and material analysis instruments.

NEC employees pride themselves on making a wide variety of Pelletron accelerator systems to meet customers’ needs. To date we have manufactured over 230 Pelletron systems with sales in over 50 countries throughout the world. These systems produce ion beams of essentially all stable nuclei with energies ranging from a few keV to hundreds of MeV. The Pelletron is the world’s only commercially available accelerator that incorporates an all metal and ceramic acceleration tube with no organic material in the vacuum volume.

Pelletron systems range in size and configuration from the highly versatile 25 million volt tandem Pelletron at the Oak Ridge National Laboratory (the world’s highest voltage accelerator), to dedicated analytical instruments using MeV ion beam technology. MeV ion beam instruments are available for standard RBS analysis, channeling RBS, PIXE, micro PIXE and micro RBS, very high-sensitivity Accelerator Mass Spectrometry (AMS) and a wide variety of other materials analysis techniques.

The Pelletron gets its name from the metal pellet charging chain, which is an essential part of the Pelletron technology.  The pellet chains are highly efficient, provide long life, need little maintenance and provide extremely stable terminal voltage conditions.

A wide range of vacuum, metal/ceramic and beam handling components have also been developed with the Pelletron accelerators over the last 50 years. These components, as well as our ion sources, have proven to be reliable with extensive use in our Accelerator Systems worldwide.
