Synchrotron-like performance in the home lab

MetalJet E1+

From limited synchrotron beam-time to 24-7-365 availability in the home lab

The Excillum MetalJet E1+ 160 kV is our latest addition to our high-brightness MetalJet series of X-ray sources.

At 1000 watts, the new MetalJet E1+ delivers 17 times more X-ray flux across a broad spectral range compared to a 30 W conventional tungsten-solid-anode microfocus source with the same 30 µm spot size. In the spectral range of 24-29 keV where the indium and tin characteristic emission lines are present, the flux advantage is as high as 100 times.

Built for 24/7 continuous performance

The MetalJet E1+ is designed for high-throughput, 100% duty-cycle operation with up to once-per-year preventive maintenance cycles. This eliminates the need for frequent filament changes as required by traditional tubes.

Sub-µm positional stability

Although running at a high thermal load of 1000 W, the MetalJet E1+ maintains a positional stability of below 1 µm during continuous long-term operation.

Unprecedented 24 keV indium Kα emission

For applications requiring focused or collimated high-energy monochromatic radiation, the MetalJet E1+ delivers unprecedented power into the 24 keV indium Kα emission lines. See e.g. the 1.3×1010 ph/s/mm2 example when combined with Montel-type focusing X-ray mirror.

What some of our customers say

CSIRO

High-definition X-ray fluorescence imaging

Because we’re doing imaging where we scan a sample through the focused beam spot, any fluctuation in the intensity of the beam will be visible as an artifact in the image. So we’re very sensitive to this, and our imaging has proved to be just brilliant. It’s clearly the best quality XRF imaging with any source.

X-ray phase-contrast imaging

Whereas a typical CT scan only lasts three to five minutes, some of these devices we end up testing for weeks. So in that case, you need a continuously running source that’s able to manage that imaging demand. No other sources really last that long. That’s a pretty clear benefit for us.

Hard X-ray Photoelectron Spectroscopy (HAXPES)

By introducing home-lab HAXPES [with the Excillum MetalJet D2+ at the core], continuous measurements for 24 hours a day, 365 days a year became possible. Previously, we were always limited by the available beam time and suffered from long waiting times. But with the HAXPES-Lab we could measure many samples with much faster turnaround from sample preparation, measurement and analysis to refined experiments. This allowed us to significantly accelerate our research and the result was a remarkable improvement in scientific output.”

Single-crystal diffraction

…with the old source you had to collect one full data set overnight… Now, with the MetalJet, it took less than an hour even for an extremely small crystal.

Na Yu, Senior XRD Engineer

Max Planck Institute

X-ray Emission Spectroscopy (XES)

Our own instrument allows us to do in-house dispersive X-ray emission from 2.3 keV, which is lower than what we’ve ever measured at a synchrotron. It gives us a much larger accessible energy range and, of course, we have access to it 365 days a year, as opposed to a few weeks a year. So, it really changes how much exploratory research you can do, how much you can test ideas, and so on.

Aarhus University

Small Angle X-ray Scattering (SAXS)

The higher X-ray flux enables new types of experiments that were not feasible to do in a laboratory before and we can even do measurements in the time range of seconds and thus be able to repeat it many times to get better statistics.”
