This is a simple description of the MIXRAD Nikon X-ray tomograph installed at NECSA, ZA
- The source voltage is 30-225 kV with a electron beam current of 1 mA.
- Anode material: Mo; Cu; W; Ag
- The source spot size is 1-3 um.
- The emission cone is 25 degrees.
- The detector is 400x400 mm, with a 200 um pixel size (2000x2000).
- The source-sample distance is at least 61 cm.
- The source-detector distance is 1.147 m.
