National Electrostatics Corporation (NEC) is the world's leader in the manufacture of electrostatic ion beam accelerator systems. These systems produce ion beams of essentially all stable nuclei with energies ranging from a few keV to hundreds of MeV.
NEC employees pride themselves on making a wide variety of ion beam systems to meet customers' specific needs with a conservative voltage rating. Although many individual models and customizations are available, they can be divided into three distinct classes:
U-Series Pelletron accelerators provide
ion beams from 500 keV to hundreds of MeV.
Terminal Potentials from about 4 MV to >25 MV
S-Series Pelletrons provide ion beams
from 300 keV to 20 MeV.
Terminal Potentials from <1 MV to about 5 MV
Open Air Systems for ion beams from about 1 keV to 500 keV.
All these ion beam systems are unique. No other manufacturer can offer high energy ion beam systems with an all metal and ceramic accelerating tube assembly. The NEC acceleration tube has no organic material in the vacuum volume. It can be baked to provide ultra high vacuum conditions and an ultra clean environment for beam/target interaction.
The NEC Pelletron accelerators utilize the world's most durable high voltage charging system. The metal pellet charging chain has proven itself in about 150 accelerators world wide to provide long life and low maintenance while providing extremely stable terminal voltage conditions.
NEC also manufactures all of the ion beam handling components and many ultra high vacuum components used for accelerator systems. Positive and negative ion sources, lenses, beam profile monitors, slit systems, Faraday cups, and many other components are available in both standard and custom designs.
