Beamline Insulators


The NEC beamline insulator provides complete electrical isolation with ultra-high vacuum compatibility on beamline systems.



Beamline Insulator Applications


High Voltage Ion Beam Accelerators

NEC beamline insulators have been very effective in isolating sensitive detection equipment from electrical noise that may be generated by very high voltage ion beam accelerators. Although there is no voltage specification for these insulators, customers have reported maintaining a potential difference of 6–7 kV in clean, dry, ambient air.


Exceptional Mechanical Strength

These beamline insulators also have been used for a wide variety of special applications that require exceptional mechanical strength and the ability to withstand thermal shock.




The standard beamline insulator has a 4″ O.D. steel ring at each end and a single insulating gap of 1/2″ width. On request, a 6″ O.D. version can be provided, as well as multi-gap assemblies of either version. A wide variety of end flanges are also available in addition to weldable tube ends.



Please contact NEC for more information on design options, or advice on which available design would be best suited for your application.
