MetalJet C2 

The MetalJet C2 offers an attractive, cost effective version of the MetalJet source technology with simplified electron optics producing a round electron beam focus. It is similar to a standard solid target x-ray tube, but features Excillum’s unique liquid metal jet anode technology and advanced electron optics. The MetalJet C2 delivers significantly higher brightness than a solid-target microfocus x-ray source, with an excellent spot quality. With the MetalJet C2 you will get a high-performance microfocus X-ray source, at a competitive price. If you in the future need even higher brightness than what is achievable with the round electron-beam focus, you have the possibility to upgrade to the MetalJet D2+, to get the world’s brightest microfocus x-ray tube.

Technical Specifications

Resurs 4

1) Room temperature liquid gallium alloys consist mainly of gallium, indium and tin. They have low reactivity and low toxicity but should be handled accor-ding to their safety data sheets and local regulations. The currently available anode alloys are ExAlloy G1 with 95% gallium and ExAlloy I1 with 21% indium (see typical emission spectra on next page).

2) The actual power used is dependent on spot-size and voltage. Maximum power allowed by the software is 200 W, however, maximum output power of the 70 kV high-voltage generators is 300 W.
3) Standard deviation.
4) Without a shutter (24.8 mm with shutter).
5) Without a shutter (10.5° with shutter).

6) E-beam spot size, similar to the x-ray spot height. The x-ray spot width will be smaller.
