MetalJet D2+ 160 kV

The MetalJet D2+ is the latest version in Excillum’s line of extreme brightness x-ray sources, following the success of the earlier MetalJet D1 and D2. It is similar to a standard x-ray tube, but features Excillum’s unique metal jet anode technology and advanced electron optics. Within the 5-30 μm spot-size range, it delivers significantly higher brightness and power than any other available microfocus x-ray source on the market. And it does so with an excellent spot quality. This makes it an ideal source for any microfocus application requiring shorter exposure times, higher throughput or better signal to noise.

 

Features and Benefits

  • Extreme microfocus source power

  • Optional shutter

  • Superior spot quality

1) Room temperature liquid gallium alloys consist mainly of gallium, indium and tin. They have low reactivity and low toxicity but should be handled according to their safety data sheets and local regulations.

2) The actual power used is dependent on spot-size and voltage. However, maximum output power of the 160 kV high-voltage-generators is 640 W.

3) Standard deviation

4) Without a shutter

 1) Actual e-beam spot has a 1:4 aspect-ratio line focus, but the projected spot dimension is essentially circular. True round focal spots for, e.g., large-angle imaging can typically generate ¼ power compared to the numbers above.
