Beamline Insulators

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

These 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 to 7kV in clean, dry, ambient air.

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.

Design
The metal/ceramic bond is accomplished by a unique metal diffusion process for bonding alumina ceramic to titanium.  Rigorous testing was performed on this assembly and it was continuously found to be leak tight.

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