Beamline Components

NEC manufactures a complete line of all metal and ceramic, bakeable beamline components for ion and electron beam systems.  While many components are custom made below are some more common components.

Beam Profile Monitors

Beam Profile Monitors

NEC Beam Profile Monitors (BPMs) provide a continuous scope display of the shape and position of the beam cross section in both X and Y coordinates. They can monitor beams of electrons, ions, and energetic neutral particles.

Steerers

Steerers

NEC provides both magnetic and electrostatic ion beam steering components including, but not limited to, neutral trap deflectors and raster scanners.

Product Info

Lenses

Lenses

NEC provides both magnetic and electrostatic ion beam lenses for various focusing needs including, but not limited to, quadrupole lenses, microprobe lenses, and einzel lenses.

Product Info

Velocity Selectors

Velocity Selectors

NEC Crossed Field Velocity Selectors provide mass and charge analysis. Various models are available for use in high potential terminals and for analysis of exterior ion source beams.

Product Info

Acceleration Tubes

Acceleration Tubes

NEC acceleration tubes are the best in the industry and have proven to be very reliable in Pelletron accelerators of all sizes. They provide a complete insulating barrier.

Product Info

Beamline Insulators

Beamline Insulators

NEC beamline insulator provides complete electrical isolation with ultra-high vacuum compatibility on beamline systems. They are very effective in isolating sensitive detection equipment from electrical noise that may be generated by very high voltage ion beam accelerators.

Product Info

Insulating Support Posts

Insulating Support Posts

The NEC ceramic/titanium insulating support post is ideal for applications that require the holding of high voltage gradients while under significant compressive loads.

Product Info

Vacuum Valves

Vacuum Valves

NEC vacuum valves are ultra-high vacuum compatible and allow rapid and reliable closure. Metering valves, right angle valves, and straight through valves are available.

Product Info

Rotary Vacuum Feedthrough

Rotary Vacuum Feedthrough

NEC magnetic coupled rotary feedthroughs are ideal for applications requiring the transmission of high speed rotary motion into ultra-high vacuum environments. It is used to measure beam cross sectional shape.

Product Info

Vibration Isolators

Vibration Isolators

NEC vibration isolators significantly reduce vibration transmitted by turbo pumps or cryopumps to target chambers, microscopes, wafer processing chambers, end stations, or other vacuum apparatus that must be kept motionless.

Product Info

Titanium Sublimators

Titanium Sublimators

NEC titanium sublimation pumping systems are ideal for fast pump down and high loads of chemically active gases.
