Hector
Description
The High-Energy CT system Optimized for Research or HECTOR is the workhorse of our systems. It is equipped with a 240 kV X-ray tube from X-RAY WorX, and has recently been updated by the installation of a Varex XRD 4343 flat-panel detector with CsI scintillator and a rotation stage able to carry samples up to 100 kg. Mounted on a total of 5 motorized linear stages, and with a source-to-detector distance of up to 2 m, this system covers a very wide range of samples with a best achievable spatial resolution of approximately 3 micron and an image resolution of 2880×2880 pixels. Two additional piezo stages allow for an exact positioning of the sample on the rotation axis.
