Accelerate industrial inspection
Enable sub-second in-line CT scanning. And ensure unprecedented yield in battery inspection. At 160 kV, the industry-leading MetalJet F achieves the world’s fastest CT scanning with micrometer resolution – now in a more compact, integrated format designed for 24/7 throughput.
Expand the horizons of scientific discovery
Measure smaller crystals. Perform ultra-fast micro XRF mapping. And explore new frontiers in materials science and biomedical imaging. Reengineered with insights from more than 200 MetalJet systems worldwide, the new MetalJet F series pushes the limits of research to offer higher resolution, faster scan times and more flux than any other microfocus X-ray source available in a home lab.
Sharpen your focus
MetalJet F brings even higher power to the world’s brightest microfocus X-ray source. Add to this an innovative pump design with zero moving parts, fewer electronic components and automatic cathode alignment, and the result is an entirely new platform designed to get more pioneering work done, every day.

MetalJet F models
- F1000 series
Sources that can run up to 160 kV acceleration voltage for the highest throughput requirements. This comes in two variants: F1016 that has a maximum power of 1600 W and F1010 that can reach 1000 W. - F100 series
Sources that can run up to 100 kV acceleration voltage and that are completely radiation shielded when shutters are closed. This means that they are suitable for applications where opening and closing of the X-ray cabinet is needed (eg for sample handling). The F110 runs at 100 kV and 1000 W. - F10 series
Sources running up to 70 kV acceleration voltage. They are self-shielded like the F100 series but limited to 70 kV to accommodate easy installation of MetalJet F in cabinets that have been designed for earlier generations of MetalJet sources. There are two variants: F12 that is able to run at 250 W and F15 that brings the most out of the 70 kV source at 500 W.

6) ExAlloy-I2 is not molten at room temperature and therefore requires heater jackets, two separate chillers and some additional maintenance. ExAlloy I2 is not available for F12.
Installation and operation
The source consists of the source head, the jet pump module, a high-voltage generator, a power module and a chiller as shown in the picture. The jet pump module must be located below the source head within certain distances. All other modules are connected with 5 m long cables. Sources operating with ExAlloy-I2 are equipped with heater jackets around parts in the alloy recirculation loop (not shown).
The source can be remotely operated through TCP/IP or directly through the GUI if it is equipped with monitor, keyboard and mouse. An API is available for integration with external software applications.
The MetalJet source is intended to be incorporated into or assembled with other components such as radiation enclosures, safety systems and radiation detectors.

7) Examples are based on simulations that typically correspond well to experimental validation. Please contact us for details on such simulations vs. experiment validations including experimental method.
8) The spot size is measured as the full width at half maximum (FWHM) of the X-ray intensity distribution integrated in the horizontal and vertical directions respectively. The X-ray spots are realized by various degrees of e-beam line focus with a maximum aspect ratio of 6:1. Actual spot size may differ depending on viewing angle and may have different width and height. Please contact us for more details.Â
