Excillum MetalJet and NanoTube X-ray Sources

Direct supply of Excillum AB high-brightness liquid-metal-jet MetalJet sources and submicron NanoTube systems for advanced research and industrial inspection.

MetalJet D2+ Microfocus X-ray Sources

The Excillum MetalJet D2+ microfocus X-ray source delivers exceptional brightness in the 5 to 30 micrometer spot-size range. By utilizing a continuously replenished liquid-metal jet anode, it overcomes traditional thermal limits for demanding laboratory diffraction and imaging.

Spot 5–30 µm
Power 250 W
Voltage up to 160 kV
LaB6 cathode

Industrial Kilowatt MetalJet E1+ X-ray Sources

Operating at 1000 W, the MetalJet E1+ delivers up to 17 times higher X-ray flux than conventional microfocus tubes at the same 30 µm spot size. Positional beam stability below 1 µm enables high-throughput in-line non-destructive inspection and rapid 3D computed tomography.

Power 1000 W
In lines 24 keV
Beam drift <1 µm
24/7 duty cycle

High-Performance MetalJet F Source Series

The MetalJet F platform incorporates a high-pressure electromagnetic pump with zero moving parts and extended cathode longevity. Optimized for 24/7 industrial inspection and sub-second battery CT scanning, it provides maximum reliability and unprecedented imaging throughput.
